i think blue works more well, if she's all green it doesnt work well with her clothes, but reguardless, nice work, i love the dynamic poses you use although her face seems a bit too squarish and pointy around the chin and i dont like how the colours are a bit plain without detailed shading (but thats my opinion), but other then that i see nothing wrong
oh and also if you post a new picture, dont be afraid to double post, im sure no one realised you posted this picture because you only updated your old post, it wont show on the forum other wise, i only saw this picture because i randomly looked at the fanart thread
and one more thing, do you have a deviantart? i'd love to see some more of your work
