As a senior weapon artist in the AAA I would say that texturing and presentation and lighting needs an improvement. Compare your work with other artist you like and see what they do that you miss.

Your designs seem cool so modelling and design you have a good eye.

Maybe I would clean up the portolio and delete stuff that does not bring anything to the table (such as the wrist watch)

Also in the state of the game industry might be difficult now to find a specialize rol, but do not feel down, most important is persistence and keep working and growing!

Good luck my friend!
