I really like this piece. Scenery is one of the things that I've never got into making even though I always intend to! I also have a Lizardman army & would love terrain like this. Do agree that it would be better with some difderent colours in, I think sandstone type colour is really cool for lizardmen scenery.
7.5 nice little set. i like the creepers. the only niggle that i have is that it looks too grey. maybe a little brown mixed in would help add abit of variety to the colour
