Although this still looks somewhat sketchy it looks really amazing. The details that you have drawn the leopard with makes him look so much better!! I am glad to have accross this drawing.
His jaw and mouth seem to be more detailed the rest of his body. Personally I find that what you have detailed gives this drawing more depth. What helps your drawings impact is his open mouth. I actually find this drawing fearsome but very lovely. Your emotions are evoked quite nicely.
Frankly even his whiskers make this drawing give an impact ... I find the technique you have used here original and skilled
