Its looking ok but you do need to make a few changes for it look more interesting. The sand is too flat you need to add some depth to it. Higher at the bk sloping down towards the front. The wood looks fine but the rocks don't look right the way you have them. Instead of having them in a circle around the wood make it look more natural if you know what I mean. Space them out more and have them staggered. Hope this helps. It just takes time to get it right there is no rush, just keep messing with it until you are happy with it.
Cheers, lee
Thanks Lee, I have more sand to go in that was just a layer to place the rocks as I wasn't comfortable putting them on the glass. I'll have a bit more messing around tomorrow bit late now.
