Where can I find specific tutorials I am looking for?!!!!!

I am trying to find tutorials on sculpting in a certain style. I love the style with a blend of reality, and fantasy. Much like the characters on Overwatch, but more precisely like the art of Jon Troy Nickel,

My biggest frustration is that I want to learn how to sculpt like this, and I don’t mind putting in the time and effort I just need some good resources for that style. The few thingsa I have found already have a pretty defined base mesh which defeats the purpose for me?

Does anyone have any recommendations?

Thanks,
