Cliff and Rock Face texture attempts

shrogg

Hello everyone, I'm quite new to the whole texturing world (Even though I have worked on games a lot in the past, but never for textures) So Now my goal is to stop this irrational fear of textures and make them while improving my skills.
Here are my latest attempts at rock face textures, as well as a shader i built in Unity/Shaderforge.

My workflow currently consists of zBrush a base mesh, Use Maya/TURTLE to bake down some starting maps and then Using dDo to get some good masks and the final touches are just some good ole photoshop.

The first one looks pretty good. On the second, the shape of the strata doesn't feel quite right, though it's hard for me to say exactly what's off without seeing your reference.

The second one was designed to be blended on the edges of the another rock texture, So the height doesn't really matter, as its more about the width.

Here is the reference I very loosely followed
