A separate post showing my progress for the Ruby painting (Photoshop).The initial picture was done on my own, trying to get the hang of digital painting. Afterwards, my lecturer coached me on painting style (such as tips on shading and drawing the outlines here) and colour, resulting in the base painting.

Afterward, he took the reins and used several adjustment layers to tweak the lighting on both Ruby and the background, resulting in the final piece you see here.
