Looks pretty good! And welcome to the art forums. 
First of all, welcome to the Fan Art community!
Really good stuff you submitted! If you're looking to do more dynamic poses, there are plenty of comics out there you can draw inspiration from. If you want something more CoX inspired, there are PLENTY of people around here more than willing to offer up their characters as reference material.
Anyway, I look forward to seeing more of your stuff and hope you enjoy getting to know the rest of us around here!
Nice, pretty good!
Welcome to the forums!
Yes, a tablet would help a ton. 
I have no clue how I survived without one for so long. 
PS: What program do you use to do those?
PSS: Do you take requests?
Thanks for the compliments!
I'm not doing any requests/commissions right now until I do all the people in my SG who have asked for portraits, and there are a few left who want them. Maybe after that, though. I'm glad you like the art enough to ask!
Programs are a combination of Flash and Adobe Photoshop - using Flash to clean up line art and Photoshop to do better color.
Oh, and by the way...
Watch out for Thor's Assassin. I'm sure he'll be by shortly to ask for a commission.
Rowr too, and maybe even Katfood as well.

Hi, forum newbie, but coming in on a whim to get feedback about fanart. First time posting, please be nice!
Electric Youth - My Blaster
Captain Ghoul - Scrapper (from my SG on Virtue)
There's a picture of my scrapper and some other varied fanart in the gallery but it's not all good.
I want to work on more dynamic poses since these are kind of "portrait" rather than good superhero action shots. Also I want a tablet to improve my line quality, but, one thing at a time.
And yeah I have no sig or avatar yet - just getting the hang of this.
Thanks if you read the thread or have any feedback!
