I think it looks pretty good!
I think there are several places where the pixelling is a bit messy and the character would benefit from larger clusters of pixels. This ties together with the biggest weakness, in my opinion, which is readability. If you already know what a Sload is, I'm sure it's not a problem, but I had to google it to really understand the shape. So maybe reduce the level of detail or find ways to exaggerate the anatomy. Or both. It's such a weird creature.
The position of the feet also makes me wonder what angle I'm looking from and how the Sload is positioned. Is it standing, sitting, jumping? I can't quite tell. Someone with a better grasp of anatomy might be able to do a good edit.
