Wow, C6, you've got some really nice looks there. I really love the different costumes for Deadbang...I always thought it was cool when Bats had his special arctic gear, or what have you. Now I want to make alternate versions of some of my costumes....
Red Sovereign is cool, but I definitely like the CO costume best.
I've already told you how much I like Hardpoint. He looks pretty awesome, like a secret agent with superheroic elements rather than a straight up superhero. Would this second costume be the Golden Age version?

I LOVE that Nighthood. I've been trying and failing to design a traditional looking superhero, cape and tights with a Batman?Red Robin vibe...but I haven't been able to come up with anything that looks original enough. You've manage to hit a really solid design with this guy, though. Really nice color scheme and choice of patterns. I'm jealous!
Spartanic is just plain awesome. I love that guy's look, classic with elements that make him unique like the helmet and gloves/boots.
I've been trying to design a winged character that wasn't just a straight rip-off of either Hawkman or Angel, but I think I've finally hit something decent today. I'd love some critiques, if anyone cares to share their opinions. I give you, Air Ace:

I tried to give him a classic superhero, tights kind of look, while bringing in Pulp elements. He's a gadgeteer, and I'm trying to think of a twist to give him as he progresses.
