Show Me Your Spines!
How about some info on the character. Origin, bio, etc. It would give us a clue as to what you might be looking for.
Indeed some info would help.
P.S. Is that a custom paintjob on a pc in your avatar Umber?
I was thinking of rolling a spines/fire or spines/elec, but mostly was curious what looks and designs other people have managed to make work for themselves regardless of build.
The sig pic was created for me by a fellow SGer, right offhand I'm not familiar with the process they used to produce it.

I mean haven you given any thought as to where his/her powers cam from? For example my Plant/Thorn Dom (I know not spines, but I think they have the same options.)
These are older images, I actually updated her thorns to have red tips. Using the metallic spines gives you these ice picks and go very well with my flora based character.

OK, I surrender. After 5 years of CoHing I've yet to come up with a costume idea that works worth a darn with spines. Even with the new power customization options I still can't make a design that isn't eye-bleedingly awful. So I call out to the costume masters, show me your awesome spiney screenshots that I may finally get a spines past the tutorial!
