Blues and details look great, the metallics need some wok though. I can't tell wether that's gray or boltgun drybrushed on the blade. Try painting the whole thing with a mix of bolgun and black and highlighting with boltgun then silver on the edges. The gun do the same way but do the silver on the rivits and top edges as well. the face looks good and the eyes are nice (not the typical staring scared expression some people end up with). I like the simple base also (seems like everyone nowadays is fighting from on top of a big rock). Cool overall, especially for a quick job!
