Colouring: I really like the mood you gave every scene. The brightest parts are being contrasted with the darker ones, and you created hundreds of hues with who or three tones. Specially in the middle one. Admirable. However, you used more or less the same colours (in their different values) for the whole composition; blue, violet and grey. Which creates a wonderful harmony that gets broken by the green ayes. This green is a stranger, you can't find it anywhere else, so it's not integrated, catches your attention, not like a focal point but like something that shouldn't be there. In my opinion it could be easily settled adding just a little bit of slightly green hues to the sparkles in that part.
Anatomy: The variety of poses is touching, they aren't violent but seem to be coordinated and respect each other's space. Their bodies are different from the normal ones, and that makes them very attractive. Maybe you should be a little more careful with the hands, but it's the same story as always. Hands are any artist's curse.
In general; really amazing piece, congratulations. BTW: I love sparkles
Love especially the second scene. The sparkles on the background are very nice and you still can see the figure. In the first scene the contrast between background and figure are a bit low, which doesn't make him jump out of the picture. The sparkles from his hands are nice done, but maybe you could have refelected the pink/white light to hise clothes and face, because it's a light source as well (same for the sprakles at the third picture).
I do love the fact that you've drawn three different poses with different use of sprakles and a different atomosphere. Really well done ^^ The anatomy and the fur looks good, but the hands could use some practice.
Overall: I think these are good drawings. The sparkles turned out really well, especially in the first and second drawing. Good job!
