Game Icons - Art Test

Got word from Roger Chamberlain that there was a possible position open to do some icons at DireWolfDigital. He asked me to do an art test since my portfolio isn't particularly chock-full of icons.

I'm worried that I tried to fit too much detail to the icons' detriment. And the time spent on these is going to be troublesome if I'm going to attempt more than four a day at the same level of artist's anguish. I suppose I'll have to budget out "stare at drawing for an hour before doing anything".
