Waterfall

Incredible! I don't think I've ever seen a marbled landscape painting as visually strong as this before!

I feel that the colours and composition are well-defined thus making it easy for the viewer(s) to make out certain landscape elements such as the falls and the river.

However, I also feel that the use of contrasting colours like mustard yellow and merlot red make for a somewhat dissonant colour scheme for some viewers including myself.

Apart from that, I consider this a positively hypnotic illustration that effectively uses marbled painting techniques to create a unique landscape. Very good job well done!
