Squares

I was browsing through a graphic design book that I got and saw a design that was quite similar. I tried to interpret it in my own way and that is what happened.

I guess it's not really the final image that is important but what I learned while doing it (yes a terrible excuse for a badly done design).

So what is it that I learned? In this design I became more particular with using the grids (hence the title). I also figured out some uses for using layers as clipping masks. And also the effects of a soft brush.
