Thanks everyone for the compliments. I must say I had some good advices in another forum, but I also decided to: not be afraid to take my time, and redo what I don't like.
So, it's not false to say I have redone at least most parts 2-3 times...but now I get what I want more the first time, so...it's a process. LOL!
Done my own nurnies below the nose. Also added the pitch stabilizer (Black round thing, like the Defiant model in terms of shape and size). Took my an eternity fixing symmetry problems...I don't know if the model have moved but it was so long to fix. I also tried pre-made nurnies, but importing shapes was messy for some reason. I found a way for making tubes with the bend deformer...it's the one I understand better.
