This piece immediately caught my attention simply by how much of a contrast there is between each part of the fore, mid, and backgrounds. The colors are vibrant, the lines are crisp, and yet barley noticeable in the overall effect.

There are only a few minor things that you may want to consider for either a touch up, or for future works. First and foremost, you have a beautiful range of light to dark on the snails and their shells, as well as the stems of the foreground mushrooms, but a few other areas such as the under part of the mushroom tops, the faeries legs, and the petals on her skirt/belt seem to be lacking the darkest parts of that color range. By adding that last little touch, it will help make it all feel more balanced rather than slightly unfinished.

Also, for the most part, the faeries anatomy is very proportionate and believable, but there is one part that caught my attention. Her left forearm is the same length as her upper arm, if this was intentional then by all means ignore this part, but in regular human/oid anatomy, the elbow down to wrist of an arm is 2/3s the same length as the upper arm. So effectively, from the elbow to midway across the hand equals the same length as the upper arm.

Overall though, this is an amazing piece and I truly enjoyed everything about it.
