Interface Design on the Web

Hey all, this is my debut!

I am developing a small publication as a college assignment, it's about web interfaces. All throughout the publication I'll be representing the current state of user interface on the web, so if this shot seems trendy, it's because it should be. This is a part of the cover art.

It will be printed, so I'm not looking for pixel perfect, this is just an Illustrator file zoomed at a certain level.

Those two rounded squares are supposed to look like buttons.

Would love some feedback!
