Cauldron Bubbles - Cottage Texturing

Today I worked for a little bit on the cottage texturing. I used Mudbox for the chimney and base of the house and used Photoshop for the rest of the textures in the photo. I want to add vines to the side of the chimney to give it more character. And while sitting here watching it render, I think I should add some more moss going on the bottom of the chimney. Does anyone else think so?
