T, rex model concept/ lineart

This is the concept I have in mind for my rex model. 
note the legs are not in an actual standing pose, they are just posed for modeling. (if I get any comments on that, I will assume you didn't read this, and I will Shame accordingly )

I blended the tail feathers into the tail and torso accordingly. (something Saurian hasn't done)

Colors are based off of Swainson's hawk, American Black Bear, and American Alligator.

I would like to thank for his help and advice on anatomy!
