I'm a "carp" too, pretty much, but here's a shot at the star:
I believe it technically matches the shadow on the font as both drop down 7 pixels and shift over 4.
Somebody else could probably do it better, but if it's useful and you want the original I could pass you the file. If you're using Gimp what file format does it use? Photobucket doesn't seem to accept Photoshop psd files.
I copied the star behind itself, shifted it over the same number of pixels as the shadow is dropped on the font, and filled in with the right color. Had to sort of draw in the fill, so a pro would know what to do there, but maybe it worked.
Also used a thinner border on the star to imitate the font and I think it came out a bit sharper too.
In any case I think the shadow will look a bit odd on the star even if it's technically correct because of the angles.
