Zombie Boss Concept- any finishing tips/ideas?

[ChantalFournier]

I don't want to micromanage something that isn't even my job, so take this with a grain of salt but normally concept artists don't do concepts for GUI. That's the UI designer's job because UI design is a specialty that concept artists are not trained for. It's graphic design crossed with ergonomics and often has very little to do with illustration (unless you do like Diablo where the mana counters was stashed in bottles and stuff like that, but even then, most UI design was not illustration.) So if you are working on a mod or an indie game or something like that, it might be a good idea to mimic a normal work structure for future reference :)
