Hi, sorry for the delayed reply. I haven't really enhanced it any further.
As long as the resolution is ok, you can pretty much add additional graphics to the DDS file to make it more deathstar like, and if you do manage to tidy up the graphics I could help you with the putting in weapon/aura/ability etc. mesh points.
Reducing the min and max shadow to 0.0 and 0.6 respectively will eliminate the too bright look when zooming out.
One thing I will say: I tried doubling the canvas size of the DDS file and it defininately makes the image much less blurry when zooming in close. However, it pushes the DDS file to 9Mb to 12Mb in size... which is a high price to pay.
What might be a better approach would be to seperately UV map the upper and bottom hemispheres of the overall mesh, and use the same texture area (the only unique parts of the mesh that are worth individualizing is the main laser area and possibly the middle wrap around area (which is nice to appear unique.
However, that will take some mesh re-design better left to those (you?!) that are more capable in 3ds max and UV mapping.
