...the model is an interesting one. Kinda has an alien technology feel and look to it.
The texture is most definitely what's holding this model back, and garnering most of the negative comments.
C&C:
As is, it is boring, lifeless, and lacks the detail necessary to make this a viable model. It hurts my eyes, and brain, just looking at it, trying to figure out what the heck it is.
Since it appears to be beyond your skillset (
not your fault), allowing someone on these boards to UV MAP and create a properly laid out texture scheme would make a dramatic improvement, and be a very wise thing to consider doing.
Plopping a simple texture, no matter how much time you've invested in it, over the top of this model, without a proper UV Map, is
never going to improve it...
