Well...if you reaslly want what I think..they are overall good enough designs.
The pumpkin could use some work, as frankly, it terrifies me. The snowman is cute, but could use a bit of a more Res look to it.
The others...need some work. By whcih i mean in an artistic sense. As ideas, they're fine. But I would suggest working on paws, (rather than what appear to be hooves on the Egg-canine?)
As for the serpent: NEED MOAR SNAKESSS. I like the idea, but um, are those wings or fins? *Trying not to sound rude.*
