Hey bags...
Great photos. [righton]
I can't give any specific 'artistic' advise as to how you should blend your photos;
i don't give that kind of advice at all. But i CAN tell you that to blend photos together all you need do is add a Layer Mask to the photo layers, then paint with black,
on the mask not the layer, over any areas you wish to 'erase'.
Give it a try and you'll see what i mean.
I also have a good tute on being creative with Layer Masks. Perhaps it can give you some cool ideas of ways to blend your specific photos.
