Aww shucks, it's charming! As for colour practice, it's pretty stellar. Lots of superb effect here. For example, white bunny and red mushroom on the tree are fantastic focal points guiding the eyes and stealing attention, only to let the viewer eyes take in the other details. The cut between cool and chill blues of the backround with the stark, neon green of the moss and gruss is pretty sweet - love how the warm bark makes a clear, distinctive border between the two parts and how it managed to unify the whole picture. It's a stellar work, doubly so for practice
