How does he look?

I don't know much about jumping, but he looks really good from what I'm seeing.

Good idea on the free jumping.

It's good he is actually trying to get over them without looking bad! He seems pretty good for not having been jumped very much!

He looks nice and round. Very nice

I think he looks very nice.
Knees up and square.
I think he'll make a great jumper.

Is it a bad thing that he overjumps when free jumping? He seems to definitely make sure he doesn't touch the fence

No, that's a good thing.

What you want as you get further with him to jump more efficiently, folding his front legs more tightly so he doesn't have to use his body as much.

Jumping grids and gymnastics, either free jumping or under saddle, will accomplish that.

The instinct not to what to touch the fence and to give it lots of air is what makes a safe jumper.
