Not bad.  We should talk...  I think this will be one of my next projects too.
Anything on the face is very difficult since we see it so often.  Maybe some
blobs to cut down on the sharp edge, but I think the main thing is that the
blue part needs a little more 'depth'.  Here's a page that goes through some
tricks to add realism:

As for the rotation, probably the most efficient way would be with a matrix
transformation:

Should be the most general and simple; it's just a matter of figuring it out.
Oh, and FYI it's probably more efficient to post a jpg rather than a bmp.  All
the same to me, but someone must be paying the bill for bandwidth.  Keep it up
though.  A good pair of eyes can add a lot of realism.
