I made some adjustments. Here are 2 slightly different ones. Wich do you thinks look better?
And here is a simplified version of the process. I assume you have some photoshop skills, or else... heh heh.
First make a simple form.
Then apply a layer of paint. Going from darker at the top, to lighter at the bottom.
Just apply a shiney somewhere near the top and youre done.
This is the simple version. If there is anything just ask. It will be easier to help when I know what you know you know?
