I have to say this piece of art seem amazing. but i also seem a few things that you need to important on ^^ first of all the waterfall's stream is a bit too white to the river below. maybe you can try to balance it little along adding a bit of shading of a darker color. the crystal gems in the cave give the atmosphere a calm and beautiful vine to it. but some of the crystal need a bit of a bright to fade glow to them. the character have a great color pallet that match with his personality. the colors of the cave are amazing choice but some areas need a bit dark shading. but the whole piece it self look amazing ^^ and I hope this help to improve ^^
