Whats his pee capacity like? :)
Liked the idea of everything(is it a coincidence or did you mean that to be Mr. Bean's car?) But there are still things to improve on.
Like making the motion of the dog seems realistic. It looked like he was a robot(maybe he was o.o, that would make sense!). However, if you meant the dog's motion to look silly, there are ways of moving the feet without it seeming like it was a robot yet capture that silliness.
Well you need to work on that (observing, and not just looking at a real four legged animal might help) and next time, go easy on the detail(for the man's clothes, the scenery was perfect and the dog's proportions were a bit off, but it was ok). Two things, detail is usually used for serious animations, however it can be used in funny ones as well, except that you need to keep in mind that you dont go overboard and spoil the drawing. I hope you can see what i mean.
Otherwise, very good for a 1-minute flash ani.
Wating for your reply,
