Didn't make direct progress on anything in particular but looked at some art, and did some pixel sketches in Aseprite. Then followed Xoppa's importing 3D model tutorials in libGDX just to see how hard it would be to get started with 3D art. (to be honest, sculpting something in 3D and making something look nice in pixel art, and poking at lines in vector art really all have a similar barrier to entry.).
Learned that Sculptris, while very easy to use and is fun to play with, does not export .mtl files and so it was too much trouble to use it as my primary 3D modeling tool. I miss milkshape (even though I didn't like it) and might hammer a nail with a machine gun by using blender instead (again). We'll see.
