Looks good! Keep it up and thanks for sharing. I'd be interested in hearing your method for developing these - just think them up, or is there a process you follow. Sky is the limit for animation and I find it's easy to get overwhelmed.
This is incredible! Seriously great stuff. I did animation in college and tried to keep up with it afterwards while working as a graphic designer, but it's a huge commitment and I found once I got away from doing it for a while, I had to relearn the fundamentals. It's still a learning experience for me 'til this day.
