Showtime as it progresses

Not sure I care for the 'every room for itself' style of basebuilding, but I have to admit it matches the personalities of most supergroups that way:
"It was a team effort. Captain Karma designed the medbay, Inferegeneous Ivan did the teleporter room, Supahuman put together the generator room, and Barnacle Bob did the entrance, petting zoo and torture chamber."

It is distracting to me that the glass walls on the right are in different positions - the top one is over and back relative to the bottom one. I rather like the look of the crossed glass pieces, why didn't you continue it with the top set?

I don't like the placement of this. I don't have a problem with it being across the way; I assume you did that to block some of the view to the medical area. But it sticks into the glass wall down below (and would above if you moved the top over to match the bottom), and having the bases of the monitors sticking out of the tops of the set below doesn't look good. I would recommend moving the monitor sets apart one more space vertically and trying to find something suitable to fill the resulting small gap. An alternative would be to set each level of monitors back a space, so that the bases don't stick out through the screens below. It shouldn't be too obvious - at least less so than the bases poking through the screens.

Also I don't like the horizontal overlap of the big monitors... though since you would need to go three wide to evenly match eleven small ones, you clearly don't have room here. How attached are you to the part sticking out that seems to contain only the one desk below and it looks like nothing above? If you got rid of the section sticking out, it looks like there would be room for the extra monitors. If there were a small gap between the monitors, you could fill it with something like one of the power cables from wall details.

Again, monitor sticking through the glass detracts from the look.

What I'm going to suggest would probably look better if you raised the floor a notch, and so might not be worth it, but... have you considered putting a holoprojecter (similiar to the one you use later trying for a portal effect) under each telepad? Keeping the arcane floor patterns, of course, having the symbol float between the symbol and the telepad.

I don't know about the sewer wheel, but I do like the podium. I'd get rid of the wheel and center the podium. Possibly put one of those arcane eyes on either side of it, and/or (if the room allows it) a defense turret of some sort attached to the sides of the podium. That would make for a proper sendoff for anyone using the teleporters. Hmm, or a stonethrower (I think that's it, head floating over a pillar thing) behind the podium as a 'talking head'.

Looks a bit spartan to me; I'd add an arcane eye to either or even both walls of blocks. Or, if the stairs are (or could be) placed suitably, a pillar in the middle.

I don't think the spike ring really fits here. It's big, it doesn't really line up with anything, and it looks like someone walking up the stairs might hit their head on one of the spikes. You'd probably be better off with some strategically placed sets of ceiling spires. Like two large flanking your inspiration tree thing, with a small one in the center pointing at it - all curving out from the wall.

I like it; a pity it isn't larger, but I think the key is it think of it as closed at the moment. Again, some individual ceiling spikes might serve well here. Like two small ones flanking the eye in the arch, and maybe two big ones farther apart, perhaps out at the edges of the arch.

Again seems a bit spartan to me. Looks like a small arch would fit in across where the rez rings are. Fill in the side gaps with small blocks, or for a weird look the modern picture frames from wall details.

In most of these pictures, the desks making up the ceiling have a few places where some don't line up - in this first picture, that may be hard to avoid with the stairs but in other places it looks just like there is an extra desk or two here and there.

I really like the stairs here. The whole construct puts me in mind of landing gear having extended down out of the ceiling.

I'd remove a glass panel from either side and add more of whatever is behind the vault door so it looks like the door is actually mounted to it (adding another set above as well). Right now the door looks too big for what's behind it. If that looks a bit odd in the way it connects to the tanks behind, another set behind the first should make it look better.

At some point in that thread, it was pointed out that SG banners in all black made a much better space background. Having seen them in person in one of stacker's bases I have to say they'd be fantastic for it. Also, this would be a good place to not have gaps in the glass. Or, if there is no access/view of the outside of this observation place, use wall items that have no back (with the invisible side facing in) as 'force fields' to keep the air in.

I'm picky, I know... the drawers bother me. I'd see if there were something to mount on it to cover them up.
