A bit of anatomy work is all, mostly on the face.

The eyes are a bit uneven, as in the right eye -which is facing away from us, should be a bit more hidden behind the muzzle/nose bridge for his head is turned.

The jaw is a little crooked.

Everything else seems pretty good.

Same goes for all the Freddles.

Maybe some work on the hands;

Here, I sketched out how the hand should look like in that position you've drawn. Just some practice will do a good deal, you're heading to the right direction! ;)
