Yes (hey you asked) lol.
Nah, not really. If you aren't happy with it though, play around with it. That left side is tough because it is just one big rock. Try breaking it up into a few pieces maybe? Then see how you can stack it from there. Also, those two stacked pieces that we can see through, they do not look sturdy there at all. Did you attach them with anything? Or are they just sitting there? I'd epoxy them in place if you want that look, but personally I would take them down and restack them in a different fashion, not a big fan of those arch style stacks.
