Super cool, although I would not use the Windows logo for the "Start" menu. Definitely change that and call it something else! I'd imagine Microsoft jealously defends that sort of thing.
I feel that direct mimicry of UIs and designs is a shibboleth of someone just starting out and starting to getting a good handle on tools.
Another is enthusiasm to share your own work with the world.
Neither is bad, but just something to be aware of.
I saw this in my own early work before I reached an equilibrium of spontaneous original designs.
