Overall ok, but the shading is kind of uncanny and the slime feels more like the skin than slime. For the skin I might suggest lightening up the shadows. You will of course have a really dark shadow, but skin is transparent and you have to keep in mind of that. You tend to have to use more hue shading for skin along with making it darker. For the slime I might add some transparency and reflections from the rest of the body to give it more of a slime feel. However, if you want to keep it opaque just add more reflections of the surfaces around it. I would also suggest taking a look at how liquids flow as well, as perfect streams don't usually come out of an area filled with water. I might also suggest working of the anatomy of the fat on your creature. It looks kind of bloated to an uncomfortable point. Keep an eye on shading, and that's it! Sorry for going all in there mate but I do see a lot of potential in you for creating demons and other wacky creatures. Make you're nightmares real, and keep up the good work!
