Wow, thank you for sharing those Carlos. I think the first, and even the second one are very interesting. I feel that especially the first is prety original. The last looks like so many of Amano's works. T he second one also seems pretty original and while I like the 3rd most of all, it looks very similar to a few I have seen before. No possibly this one was first, I have no idea there.
I do wish the photos were better as I think there is alot of detail, hardscaping, etc that is missed Any idea what the red plant on the right, in the second photo down is?
