I like the cyberpunk look you got going with the boots. I'm going for a more formal military look. What software are you using? I'm using a combo of Lightwave 3d (Modeling), Poser Pro (animation), Milkshape 3D (rigging and tweaking) and Photoshop (naturaly) .
I'm not sure in what format I'll release the finished model in, because there isnt really functional art pipeline for Quake 1 in Lightwave 3d, nor Max & Milkshape. I'll probably release it as a combo .DPM (Darkplaces) and .MDL (Half Life) model.
I use 3ds Max 10 (modeling), Lith Unwrap (uv mapping), milkshape (rigging and animation) , quark mixed with milkshape to get it in which ever format i want. also use some qme
id start from scratch again, try and follow your concept a lil closer. the concept looks cooler to me lol. (might wanna try n make up a side view too. it helps when modeling)
