Arm Cannon - E7

So, i made this design to learn about Sub-D modelling inspired by Megaman arm cannon. Tried to not add to much detail to take it easy while learning it. I must say, Sub-D modelling is fun, but managing UVs unwrapping little bit confusing. There is little bit stretching everwhere. Not the worst, but to understand how i can get better at them, time to practice more.
