i would say try blending in the render...use the smudge brush to smudge it into the background. and I agree with the previous posts although the cd4 in the background is amazing. it's all the same overtone so it takes away from the photo. try using a gradient map and play with the settings and fill levels. that will adjust the colors...or even a warming photo filter. just some ideas but you're definantly going in the right direction.
