Meh, stayed up past 1:00 in the morning to get this done
Anyways, remember that there is generally no "blending" effect from grass to sand, sand exists in clumps near beaches and just stops, thats why you get those wave like looking shapes where the grass undercuts the beach. You did a great job of making the grass spill into the sand, nice and natural looking if I do say so myself
I also touched up the corners of the mountains a wee bit, they were of a differernt palette to the other tiles.
