Photo editing

Hi.

I have two photos taken on a beach of my wife and I.

Picture A, my wife looks great but my jump is not good.
Picture B, my jump is better but my wife prefers herself in picture A.

I'd like the image of my wife from picture A and myself from picture B seamlessly merged together in a new picture with the rope joins and sea/sand looking perfect together so that no-one (not even me) would be able to notice; even after zooming in. I'd also like them to be colour matched please and the colours more vibrant.

There were 4 photos taken at the same time the other two I can include for reference and additional source material. I have included a picture of the sample shots as the actual files are too large to be uploaded here (5 MB max file size - the actual images are 6-8 MB each).

I look forward to hearing from you,

Kind regards,

Mike
