Awesome shots! Your photography has always been great.
I picked up a d5100 last year and am slowly getting better, but definitely need to practice more.
Since we're talking cameras, check this out...

I co-own a video production company and our Epic just came in a couple months ago. It's so awesome. We can shoot 5k raw images at 96fps (!) with a camera thats a little bit bigger than a dslr. Groundbreaking stuff!
My focus is really on the post production side of the biz, but being around all these cool cameras has definitely inspired me to shoot more
Anyway, again, great shots!
