Falcons,
This is a great shot... I have done alittle of this type of work with my niece pictures. The only thing is if you are layering you need to blend a bit more in my mind..
DV mentioned this is his post as well. What I do is use the lasso technic (I use paint.net but I think PS has this as well) and circle just the bare out line and then gaussian blur it to a 1 or 2. This in mho blends it so there is no line but there is still detail.
I hope you dont mind but I tried it on your pic and this is how it came out.. the lines are not as pronounced. but it really is up to you and what you like most..
Let me know what you think?? yah or nah..
Also.. how did you get it the layers to be translucent???? I have tried this but can't quite do it..
