I think the flash you made is pretty excellent. When I watch this flash and I then compare it to other flash movies in the top 50, you easily could get up there if more people knew about you. Your flash style (as the previous reviewer stated, simple but solid) works, and a lot of animators seem to follow that kind of thing.
I checked you out on Youtube and you don't have very many subscribers and the like. As far as skill goes compared to what is considered great, you SERIOUSLY NEED to get known!!
