For people who have trouble getting shaders to look nice, yes, flat toon is a good choice. Your avatar would look nicer if it were flat lit and would be a nice starting point if you'd like to go back to that and work from square one.
There are lots of people here who use lots of varying shader setups with different levels of complexity. Shaders are like makeup, you're supposed to use them in a way that flatters your avatar and helps to hide the flaws of the base model. In my opinion, the way you've configured your shader works against you and draws attention to the flaws of the model.
