Thanks for the feedback everyone!
@jblunar, thank you I added some more shadow and rim light to the rocks, and also a field blur to great more depth.
@bomjeshes You know, I forgot to flip the canvas for a while. I tried that today and found some asymmetry (both the girl and the tiger) that was throwing off the realism. I also added extra highlights to the face and fur, so hopefully that helps. I still have a lot to learn, and there is a lot in this painting that I wish I had done better. My motto for this entry has been "Finished, not perfect." Thanks for the honest critique.
@douglasderi Thank you!
This is where I'm at currently. Lots more rim light and some snow effects. I think I am done for real now. I'll try to finish up the concept sheet later today, and maybe post a process gif.
