Thank you! I have been struggling with the height of that piece as well - rule of 3rds, etc... I have a couple pieces of rock leftover (one is an arch/cave shape), so I may play around with that. I kept trying to make it taller but always ended up not loving the result. This is probably why I always finished projects the night before due when I was in art school - I'm too picky... lol! I saw some CaribSea "frag zone" rocks at Petco the other day, I may grab those and see if I can build up the height a bit with smaller pieces.Looks fantastic! You did a great job with that scape. The only thing I would do is add a bit more height to one end. Possibly build up a few more inches on the right 1/3rd area to give you some more "Up and down" and draw the eye off center.
