to0o0o goood mate... just a quick note on texturing...try using deep paint 3d...its veryy good for texturing...and as far as Unwrapping is concerned...deep paint UV comes along with deep paint 3d 2.1. and its pretty good for unwrapping , have'nt used it myself thoroughly, but have heard alot abt it
actually i m empasizing a bit on texturing cause your base model is too good and good texturing will take it farr away.,,, best of luck with it and looking forward to see more...
