I think that her arm is a bit stiff, the way they stretched back and bent, it looks almost a bit awkward. But I like the flow of her hair, I can almost feel the breeze whispering in my ears. Great choice of colours, I think they all blend well together (but then again you've been doing this for years, so quite frankly, it's to be expected). They way her head almost disappear and meet a faint splash of green on the back softens and balances the heavy green at the bottom. I also love the hints of blue and purple on her skin brings more life to her. Other than the arm, I think everything else is nice. <img src="e.deviantart.net/emoticons/s/s…" width="15" height="15" alt="" data-embed-type="emoticon" data-embed-id="392" title=" (Smile)"/>
p.s. I hope you don't mind of my critique!
