Hey Kyoteart, great work! I recommend more work on the nose and jaw line to better match the Na'vi look.

I did a paint over on one of your WIPS to show those areas I'm referring to. I made the eyes a little bigger because the Na'vi have larger eyes. I redid the nose, and used Netyri's Na'vi as a reference. I also sized up the jawline to better match your photo reference.

But anyway, great job so far. Hope to see more progress on your entry.
