I found a more effective approach to the paint over was to start in black and white so I could decide on the values and composition. it also made the photo bashing easier. I then added gradient maps and colour layers to add colour.
Feedback
the feedback I received was to increase the contrast between the creature and the background by adding a multiply layer on the creature, enhancing the rays of light in the background and making the rim light stronger. I also lightened some of the darkest values so the background wasn’t drawing so much attention.
Here I continue working into the textures and lighting. I also altered the tail to make it look more like it was wrapping around the pillar.
