Looks awesome!

And the difference in shades is so little, that I can see it only on the pic from Your by Thu Aug, 04, 2011, on the recent one it is invisible.

I think, that if You still want to fix it, it can be easily done with several molecules of pain, to make a color gradient from one shade to another, without a need to paint all the build through. With the slight shades difference it gives a wonderful optic effect, that You'd never be able to distinguish one shades frm another. Tried this a couple of times myself.
