The design looks nice. Looks very Bootstrappy though, I think it's just the hard transitions between the header image, navbar, content, and footer.... The difference between the content and footer looks nice, but the image at the top and the navbar... idk what's going on but it just seems a little off though...
Great job otherwise! I think that'll be a great tool for others to use and build upon!
