Not bad
For sprites it's not soo bad. I mean there are a lot of these on Newgrounds, and I would love to see you do somehting more in drawing flash animation.
Although it is actually very good for a sprite movie. Well sprite short.
I would say that you could have lengthened the video a bit more by showing probably the path he took, problems he faced, obsticles he had to get over.
All of that could've been added to enhance the flash. But for a short, it does tell a good story. It gets a little message out, and has the way of entertaining the viewer.
Stick to sprites and keep honing your skills. Make those videos more lengthy and it will surely stick out. You have the comedic genius.
