not a problem.
Well, hmm, is it a pond, beach, lake? Depending on which it is, warrants a different look where water meets land. As it is right now, it seems to me that it's like a huge lake and as such deserves a more muddy, fine sediment with probably some grass kinda. Naturally beaches will hit sand, and seas/oceans will hit gravel with darker sand with maybe some rocks....generally imo.
