Great retouch. The only thing I would do is equalize the catch-light on her left eye. Sometimes, I'll just clone the other eyes catch-light or create one that's similar. I find that when a picture is reduced in size, the catch-light can become distorted.
BTW, the Ducati 1098 is awesome. If everything goes well, I'll have one this winter.
Lovely! A thought occurred to me looking at Mackenzie compared to Crystal... Mackenzie must slather SPF 50 on all the time, huh? :tongue:
Nice picture of two lovely young ladies. I like your final edit. I do wonder what you used for flash in this shot and why no diffuser as the lighting seems a bit harsh.
