I think I like it.
I definitely like the contrasting light and dark sections. IMHO, I'd stain the lighter woods an oak or maybe even maple color and try to get them to match as close as you can.
Only thing I don't care for, and please take this in the friendly constructive manner in which I intend it, is the dark colored piece on top needs to be shaped to look more like it's part of the design. Being square like that it just sorta looks slapped on. I don't know what sort of woodworking equipment you have access to, but with a table saw and a router it wouldn't be much work to custom cut a piece that would really match the shape of that top section really well.
I like the direction you're going, but I would suggest that one tweak.
