I'm not sure if you're looking for criticism but I feel that there's a problem with depth in these pieces. When I see them, I feel as if the opposite side is completely flat; almost as if they've been made out of plasticine.
Scizor looks better in this respect since the shading doesn't look like a bevel and emboss layer-style whereas components such as the Tentacool tentancles and orbs do.
That's not to say I don't like this pieces, though!
They all look great and the scizor stands out due to the shading in comparison to the other pictures, imo.
