Well
It's obvious that you're learning, but I like your style already. It's better than 80% of the 'first animation' videos around here. Reminds me of that eerie salad fingers kinda flash right off the bat. Very short obviously, but I kinda like how he opens his mouth and just weird noises come out. That and the background is pretty good. Obviously could be a lot longer - that would be much more enjoyable. As it sits, it's kinda funny but there's no story and not much to watch.
I'd say you're well on your way to making good flashes. Keep up the good work.
