Hey Cindy,
The shoreline is cool. The gull is a different sharpness to the shoreline, but I'm not sure I would have picked that up without you indicating it was an overlay. The sky also seems a bit flat and the horizon line/transition to sharp. Again, not so much so that I necessarily would have picked it without a headsup. Given how tough it is to get these kind of matchups just right, you've done very well.
