Thanks a tonne for the feedback Bee-Bee, that's beyond amazing feedback to get. I definitely appreciate the time you took to write that up for me. I've actually been studying your helicopter a lot, and think I've picked up a few things that I want to try out.
I'm definitely wanting to put the time in to do this right, as I've come so far, and invested so much time, it would be a shame to stop short.
Anyway, in response to your feedback:
1.) Yea, feedback I've gotten from almost everyone, scratches really need to get toned down, so something I'll be doing for sure.
2.) UV layout could definitely use some improvement, the gaps between the small pieces are too large, and there's not really enough reason to have the sides separate. I think what I'll do is after I finish the texture, is fix up the UVs, then bake the texture from the old UVs to the new. The source texture is 2x res, so it shouldn't be a problem.
3.) I wasn't originally going to texture it, but after seeing it like it is, It could definitely help the model. I don't think I'm going to do a full high poly and bake, but more than it is now for sure.
4.) Completely agree, actually working on that right now
5.) I have to admit, the spec map was done quick and dirty, and is pretty much grayscale. It has a goss map, but only done so the glass/plastic bits are more glossy than the rest, it doesn't have any actual textural detail in it, so that's something I need to do.
6.) I love the ground bounce light idea, hadn't thought of that.
Once again, appreciate the feedback extremely, and it definitely gives me a great deal more motivation!
