I agree it needs more detail. You can spare a few more polys... one hundred or so even.
Where it needs the most improvement is texture.
I really don\'t like that texture, it looks like it\'s in the army, wearing camo gear.
Bugs don\'t look like that.
The texture should clearly show the joints in it\'s body, and fine details like a real bug would have. find a picture of a scarab beetle for an example. They have fine lines along their hard shell casing.
I found
this and
this for you, I hope they help.
Also, beetles as you may have noticed, have six legs, not four. you may have planned this, but if not you are two short.
I do like the model though.
Edit: When (if) you redo the texture... please put it on a black or white background, probably white as it is lighter. The background texture makes it annoying to try and make out the creature.
