I think the color choice was nice, however I would add more contrast so as to make the tones more discernative. Like a darker shade of yellow to clash with the more brighter color. I found the shapes to be quite interesting and I thought you should have added more of them, well not the white stuff, too distracting for my taste. The orange element at the bottom seems a bit LQ and in a way shifts my focus a bit. Overall I think the style you chose went rather good due to it being a pop-out sig but I would focus somewhat more on the composition. Because its a vert obviously the amount of space would be decrease. Try giving the canvas more width next time Did you do some DPing in this sig?
