This is really nice. If I would change one thing, it might be to lighten up the middle picture. The emotoinal connection illustrated here is wonderful. 9
Haven't commented to much on this challenge but..you have a really nice feeling flowing..this is my disclaimer looking at this on my office monitor....the exposure of the center photo should be identical to the other shots it looks too under exposed in comparison to the light bubbly feeling in the other 2 shots..if you wanted to use a title a just grandpa & me/... but there is nothing to indicate fish feeding.. you caught natural relationship between the two
The handy thing about your composition of portraits is that the "fish" are only implied...you could have shot this in Palm Springs. Excellent example of using the title to add context. Cooperative, photogenic models always help as well...
