Krazyguy75, whoo, excited to see you give spriting a try! For a first sprite, you've nailed down a lot of spriting concepts! I like the colors you've used on your sprite, and your attention to shape look great, especially on the antennae, arms, and tail tuft.
My feedback for you: The legs are on really different planes, so it looks like it's in a jumping pose rather than an idle pose. I also think the pose in your sprite is a bit stiff. The trunk of the torso is really vertical, while the tail comes out from the back horizontally. Would you be able to show a more gentle slope from the torso to the tail?

noobiess, the color of the head and arms on your sprite are a light blue, but on the main design drawing, they're an off-white, peachy color. I think the parts of your sprite that are actually meant to be light blue look a bit gray and could use some saturation. :) I prefer the pose on the left, too. It has a better line of motion.

Everyone else I gave feedback on Discord. ^^
Edit:
Churdizard: that's a fun sprite, but this sort of sprite belongs in the
CAP Fanart thread. :)
