I feel like i'm too foused on similarity, and details, I would like to make simpler images but with more character, get away from academicism

Hi! I recently got into digital drawing after being on a traditional drawing hiatus for 12 years (back when I was 21). I'm happy with how this one turned out but I'm looking for some constructive feedback, so please fire away! I think what I'm struggling with the most is finding a style. I'd love to be able to do less strokes in general and keep things simple/stylized. I love how Jon's drawing's muscles are so nicely defined too, it feels like mine are missing a bit of volume!

Hi Jon, really loving this course, I have a question regarding what brush you are using in the 'Grey scale Painting process tutorial? I downloaded the brushes just trying to find the name.
