Great work; solid, sleek, accurate and really cool. The modded legs look good, and the head is just brilliant.
However, what's that torso brick? It looks like a crossbreed of battle droid and super battle droid torsos.. It also looks a bit asymmetric, so it most likely isn't an official mold. I suppose you just cut two different battle droid torsos and glued them together? If so, really clean and smooth work.
