Okay, the mesh is making progress.
I'm working with a polycount comparable to N64-games, so it's really low

As far as I can see, I already screwed up some stuff, for example the normals seem kinda twisted around in every imaginable direction...
Anyway, it's my first model ever, so it's more of a test than a serious attempt in modeling... Friday in the evening (UTC) I'm gonna put some screens in here along with the .blend-file.
Thursday EDIT: The polycount is getting higher. Blender says, I have about 700 faces already. And I didn't even start the lower body half.
My model is built of three separate objects by now. Upper torso (including his back arms), head and jaw. Maybe if someday Nexuiz should have facial animations (like an angry face while shooting) this might come in handy.
I think, the model has some major glitches, there have to be some holes, I didn't discover yet. It's not exactly looking like my Origin-sketch, but it's cool anyway and I'm already proud of myself

Though I expect, this isn't gonna last long, as soon as I post that .blend-file and you start finding bugs all over the place.
Friday morning: Starting the legs, so it's now head, jaw, upper chest and lower chest (including the legs). Gonna upload the .blend-file today between 23 and 24 o'clock (UTC)
Friday afternoon: It looks pretty finished now. The polycount is low in comparison to the usual Nexuiz-model, but it still looks kinda cool. Maybe it's just because I finally built a 3D model myself, but I'm actually very satisfied with my work

For now.
