Geometric Blue Mountains

A little while ago I saw an abstract geometric painting of a mountain river at sunset by Mark Adam Webster and I was inspired to re-create this in just blue hues to see if I could put a different mood into the same concept. 

I discovered that painting acrylic hard straight edges is not easy by hand for a relatively small painting and that I need more practice to get this right.  I think I will revisit this using masking tape for edging to see I can improve on the final result.
