Muddy Shoreline Material - Substance Designer

For the past two weeks I've been trying out Substance Designer for the first time, and I'm really enjoying the workflow and getting quite deep into it.
This was my second material ever made in Designer, a rocky shorline surrounded with mud. It could certenly use some more debris and overall tweeking, but as it is for now, I'm pretty happy with it.

Let me know what you think? :)
