this drawing's alright. you've got a good sense of colour and ehh for form. the black contrasted with the purples and orange is pleasing to the eye (though, personally, i'd up the contrast). i like the camera angle! it shows off the pokemone quite well. i'm pretty sure there are some tangents around the purple anemone things and the hind legs.
although, to emphasis the shape, you should add more darker shadows on the pokemon. not as dark as the cast shadow, but enough to understand both the roundness and where the light is coming from. it's looking a bit flat rn
also, two nitpicks:
1. i don't like how the pokemon's staring directly at me.
2. make sure you fill in the colours properly, the are some areas (notable the anemone things) that have purplish specks where there shouldn't be.
