Hey Caleb, this is very nice work, I love the composition and it's overall very interesting. My biggest suggestion (and this is personal preference of style) but I would sharpen some line-work and add hard edges to the lions legs and to the arms of the subjects in mid ground so they stand out more and don't mesh with the background guy. I would also darken your shadows and add a wider range of contrast. Your hands and poses are great, don't be afraid to darken the lines a bit to show them off!

Looking for a critique/suggestions. I had trouble with his eye, mouth, back of his head and arms. Part of the problem was the model was so grainy. I ended up giving some detail to his eye because I couldn't make it like the model and not have it look like he was grimacing.
