I want to comment on all your pieces, but instead of spamming your inbox Ill gush about this one.
I love the greens! The background is so nice and fluid, but still gives all the foliage which is awesome. Im also in love with the perspective on this...normally Id say looking up the backside is unflattering, but the look on his/her face, and the colour pulling your eyes to the top is fantastic. Great job. <3
