Adjusting my colours
I realise my initial colour choice for the skin shadows was far too blue. I use Ctrl+right-click to select the Overlay layer I painted them on. I use the Color Balance tool instead of the Hue slider for smaller adjustments. I open it up and shift the mid-tone slider more towards the green of the environment. She now feels more settled into the jungle, rather than pasted on.
Tackle the colour of the reflection
Her real-world reflection should have similar colours but be subdued. I copy the colour layers for her figure and reposition them over her reflection. By moving those layers under the transparent colour layer for the water, they’re automatically adjusted. When you’re painting a lot of coloured light or transparency, good layer management becomes really useful.
