so this is what happened to "brother" bear from the bearenstien bears when he grew up. :) i knew he was hanging out with a bad crowd. the color ccheme is good but you need some highlights.
Base it, paint the whole gun black, then drybrush over it with metal, the fur looks like all one piece, you could try the drybrushing thing there,too, only with brown instead of metal, and the legs seem too small for the body. Pretty good sculpt overall,though.
This is a cool sculpt. Nice ears and fuzzy head. Nice gun. The paint needs shading, and might be a tad glossy. Try thin paint and start with some simple dry-brushing on the fur with a lighter brown or cream.
