All So this image is pretty interesting. the way you balanced the positive and negative space. A nice concept but i think you could have done a little better to improve this photo. a simple photoshop visit can fix this <img src="e.deviantart.net/emoticons/w/w…" width="15" height="15" alt="" title=" (Wink)" /> You can do a contrast adjustment to this photo to balance the harmony of the green and the blue. to me the green is over powering the blue. so the contrast adjustment can overall balance it. you could also do an extreme contrast then shadow/highlights adjustment to help.
That is a just a suggestion. this photo in it self has good vision. Nice job <img src="e.deviantart.net/emoticons/s/s…" width="15" height="15" alt="" title=" (Smile)" />
