I think the GRADIENT SPILL text is hard to read in the banner image, although I suppose that's a design choice. Overall I think the board layout looks nice. The only thing (very nitpicky) I don't really like is the curvature of the lines on top of each section. You kind of have this double line thing. On the left side, they seem to fit together even though the curvature is somewhat different. On the right side, the lower line has a sharp zigzag and the upper line has a smooth curve. If it were me I'd either sharpen up the top curve or soften up the bottom curve to make them fit better. They don't need to run parallel, but just need to be a little more harmonious in juxtapostion. Then again, I might look at it again in an hour and decide it looks just fine as is. 🙂 Also the top banner area looks too plain with just a rectangular image, I assume you are going to add something else up there? Anyway, it looks good.
