Thanks for all the comments! 
I've cloned out the hair now on the edited image (I haven't uploaded it though), so no more distractions there! Anyway, in actual fact the 'sweat' is meant to be a tear (it's just water though), lol - can only girls cry?
The reason I decided to keep (enhance, even) the blemishes in this shot is because I always airbrush photos, and this time I wanted to try something a little different and keep it a little more 'realistic'.
In creating this image I used Photomatix Pro 3 to HDR it up and Paint Shop Pro 9 to warp it, dodge and burn it, airbrush it, clone parts of it, 'colour' it, and so on and so forth...
No Photoshop AT ALL!
Pretty much everything has been done by hand just as an airbrushed painting would be.
