Finding the right colours
I go overboard with a range of Adjustment layers and then rein them in using the Layer Opacity setting. The results are really easy to gauge when you can adjust a setting with just a single finger swipe. I like to minimise the number of layers I use, and will regularly merge them into one layer, except for any elements that I’ve separated out. I start zooming in and play around with a lot of colour variations and detail within the different creatures and elements in the painting.
