I like the combination of orange and red/gold with the green in the background. I understand why you faded to black on the left-hand side and if you had a lot of icons on that side it would be the perfect slot for them !
"The artist is a receptacle for emotions that come from all over the place; from the sky, from the earth, from a scrap of paper, from a passing shape, from a spider’s web." Pablo Picasso
