There is always room for updates and enhacements. I can see where this can go... If you pick a nicer green for the taskbar and the start menu. Then you can hit this off. Looking to see what you can do. So dont give up. Dispise what people say about it right now. I like to look at this as a beta version a consept of what it can be..
Nice one for a first try. I like the idea. But to make it a bit better, as soemone said earlier, the text doesn't really fit with the rest on some parts. Also, I think you tried to make a too big shadow and it looks like it's been 'cut', it stops at one line instead of fading.. Kind of kills it. Try to make your shadow smaller, it'll look better.
You could also go more into an advanced style and edit the window frames so it looks less aero-like.
the shadow doesnt actually cut off lol i was piecing together the above images from screen grabs and i didnt actually notice that i had cut sloppily around the media player. yeah thats soemthing i would be interested in actually, i might try and change frames in my next one thanks
