I agree with you on the winter illness, I have been sick to, its the worst! So far these are starting to look really good. I like the costume designs you have done so far and the proportions are working really well. Keep designing and keep experimenting with different costumes. Feel better!
Hey good job man, can't wait to see them finished. I like that you captured that western feel with just a hint of nobility. I haven't read The Alloy of Law but i did read the first book in the mistborn series and I feel like this could be a character from that world.
Looks like it is headed in the right direction. Difficult to say much else as is, hope you feel better soon.
You said you were going for something kind of Steam-punky, right? That may not be the exact look you're going for, but steam punk tends to have lots of little details to it. Buckles, leather straps, etc. Maybe do a search on tumblr for steampunk, and see what you can find. People go crazy for that stuff.
The costume looks good, but work on re-designing his face so it's a little more original and appealing. Right now, he just looks like ye ol' everyday good guy face.
Good start but they need more development.
