Prop - Sci Fi Barrel

I wanted to push my hard-surface modeling skills a bit in the realm of realism. I definitely learned a lot along the way! Altogether this took about a week and a half (working in my spare time), I could have kept going on it but I feel it's good enough to post here now.
Thanks to everyone for the feedback and support!
