Portrait painting - smile

Hello everyone, how are you all today? i hope everyone is having a great day.
today i made a new digital portrait painting of guy smiling with all his teeth visible.

I haven't drawn something like this before and it was sort of challenge but i had so much fun drawing this one.

i didn't have to think about making it clean with lines or anything, i kept the sketch layer on top. And i love the result.
let me know your thoughts

here are some process shots:
