Shaping of a "Rock Block".

So one of our fellow artists by the name of Critskull who makes some pretty good pixel art of their own made this nice rock texture, and I decided I was going to play around with it and see what it'd look like if it wasn't a full block. I tried making it look more like a boulder at first, and it slowly turned into sort of a material you'd see in something like runescape. I'm fine with majority of these, I'm not as certain which is my favorite though.
