Pretty good blend...SBS would make it a lot better! (Although the forehead on our right side could use some work...).

well chopped, I agree about the forehead though - that was the first thing that caught my eye (it looks like there are some stray lines/hairs on the right if it too). Matching eyes might help too? Can we also have a high res and SBS?

Please!!! Crop it. See the ears? One is an inch higher than the other. If you crop outthe ears down to the face, you'll have a great entry.

Thank you for not retouching the older mans face to look younger!!! This is a terriffic blending job...it looks..umm..natural? jawshoewhah is right about the ears........just darkening the younger one will make this even better!
