Yeah, I didn't really know how to go about shading the "bubble" dome. :P

I like your design, especially the adorable little pipe on top, but I think your shading could use a little bit more work especially on the roof area. The pipes came out nice though.

i dont particularly like it, i think its just the dithering and non-metallicish shading.

Thanks for the feedback. You are right, they're a little flat, but I can't be bothered to put more time into detailing them anymore. :) They're for a very big map. The doors only open an close for a brief second when a Furre (sprite) bumps into them.
