Interesting textures and colors. Chocolate, icing and ? At least that's what it looks like to me :) I like the colors and the patterns. Would prefer to see some more focus in the lower left corner and maybe more texture in the upper right, it's rather bland compared to the rest and makes the image feel a little unbalanced to me.
I know your frame is very think but since your image doesn't contain true bright white I find it a little distracting, it also looks wider on the right and bottom then at the left and top. Did you use an even number of pixels when you expanded the canvas?
