This sort of reminds me of my film called LEGO Beach.

Though there may be some light flicker, and minor set bumps, I absolutely enjoy your film. The voice acting could be improved, but if it's what you've got, you've gotta work with it. I loved how you made Mark build his sand sculpture, going through multiple LEGO pieces of the same color to end up with a final result. I didn't expect a photographer to show up, but once he got into the water and said that he, "feels like he's forgetting something", the plot was a tad predictable. Even though it has a few flaws here and there, it did make me chuckle. Nice job!
