I didn't see the demo photo as an attachment to reference to unless I painted along so I decided to TRY for once being original and creative and deciding if I should just give up on acrylic.  I have attached my photo of Mt Scenery on Saba, Dutch Caribbean i used and wish I could see how you would paint it. Anyway here is my green scene. I may try this again with other mediums but I just dug out acrylics and made it up. Please feel free to give me feedback on what I "could or should" have done! Was an experiment!
