Blackstairs range study 3

The last in a series of studies of the Blackstairs range of mountains here in the south east of Ireland. Again it's acrylic on paper, 10x14 ins. I have trouble with acrylic, in that I never get used to the colour shifts between wet and dry.... I know there are open acrylics available now as well, where it's claimed, there is little or no colour shifts. I struggle with the medium, I have to admit. I would love to master it, as it would suit many of my ideas,  impasto, texture and pure colour. I get so frustrated with it, so easily.
