They aren't incredible.
Quality definitely needs to be upped.
It is pretty smooth.
The background is a little busy, there's a bunch of crap in the back.
The fact that you're only pointing out the negative portions, leads me to assume that your post was a bit more than just constructive criticism. Maybe the word "denial" will help.
Don't expect much from other people if you're only willing to offer negative criticism. Especially when your art isn't even as good as theirs.More on-topic: Nice work with the claymations. You're good at showing the usually un-noticed emotional aspects. Which is a key thing in any anymation.
It doesn't seem like you're using wire, though. Give it a shot, but don't improvise; paperclips always cut straight through the clay. A local hobby shop may have something more clay-applicable.
But, aside from that, fantastic work. And, on a side note, what kind of clay are you using?
