I don't think that cats, especially big cats, have such round heads and noses. I think they are more flat on top, but you should be able to find a good reference no probs on google. I also think that one panther should be enough, the one behind her to be specific. Instead you could try to add vegetation or such in the foreground if you plan to continue to work on it.
Other than that she has come a long way since your first sketch There's still the "crab pincer" problem with the hand someone mentioned on a previous page, and I think you could gain from fixing that. Try to use your own hand as reference, someone around you should be able to help you take a picture too I hope
