I had changed it from the blue initially because it felt as though it were clashing too hard with the orange and reds of the rest of the scene.
I'll tone down some of the sheen and see if I can find a better color for the phantom.
Thinking about it now maybe it would work better if the smaller tendrils coming through the walls were desaturated, and let your eyes more thoroughly focus on her main body.
Or perhaps I should take it a step further and remove a couple of said tendrils to make it feel less busy.
Hrmm yeah I think that will help out alot as well.
