A pic of my son on his quad bike.

Wow, what a great stopped-motion shot! I really don't know very much about this kind of shooting so a critique from me is sort of left-field. I think the one thing I'd like to change about it is to see the quad itself. The way I see it, this shot could actually be of your son stomping his feet in a puddle.
Anyway, great shot. Thanks for posting!

Yes, good shutter speed and excellant timing. I like it a lot, but wish the background was more interesting. I would crop out the top so that you cant see what's beyond the hill. Also might try sharpening it a tad.

I agree with GB and McMad...a little more 4 wheeler, a little more sharper. It definately has potential, just a few post process things you can do!

Well done and a good start,
