It took me about one month to complete this work. At first I tought that I can do it faster but it wasnt like that. I spent about 100h and I think that its worth of it.
If Im right then this picture consists 234 colors. Yes it maybe to much but what can you do.
This picture is about zen garden and monks in it. Half of the picture is zen garden and half of it is parking area and a restaurant, what isnt opened yet. Also there is a way to underground.
When you look this sand then you may see that its done like zen garden. Theres a picture about the sand as well.
So I hope that it fits with your expectations.
