Thank you! ^^ I'm glad you like his design! Usually people are intimidated by it, and as you can tell from how many times I've had to bump this that usually means I have a hard time finding artists to draw him.
I'd love for you to draw him! You have a very unique style that I think he would look quite nice in :)
About the art trade thing, it's definitely something I'd be up for! However, I'm pretty swamped with my full detailed commissions right now and probably wouldn't be able to do another one right now, but I could do a flat coloured drawing like the ones shown here as well as throw in some tu if you're interested?
Yes, Attack on Titan is awesome! :3 It's my favourite anime along side Tokyo Ghoul XD
