This is the best I can get.
I do think you still need to spend some time combing the fur with the direction of the body like on the chest and face… also I see your model is very low poly, maybe smoothing it and make it more rounded would help.
As for lights please check carefully the setting in my previous file. You need detailed shadows activated and put your lights carefully. Start with one light as suggested earlier, if you like it add a second one fill light then a kick(from the back). In my scene I didn;t name them but you can guess from their order.
