This is beautiful, I really dig this image.
small critique: tighten up the hands. They are missing the middle part that controls the fingers. Hands are hard generally but they can be figured out. Learning how to paint a couple of stock versions of hands might be an easy tool you can use in your paintings.
These hands are too goofy and distract from the other good parts of the painting.
Your melty faces from wherever and glimmering eyes are spot on.
