@justartress -
I'm not really getting alchemist from any of these designs yet. Definitely keep thumbnailing through and try to push the concept into the character more.
I like the look of the character so far - sort of a scifi-windwaker-link, but it needs something more in the costume to really take it to the next level.
Do you have a website with more of your art? I'd like to see your rendering / coloring style. (although I suppose i can just wait until you get to that point with this piece!)
Also be careful of how symmetrical some of your designs are coming along, It adds a lot of interest if you can break up that symmetry!
