Ha, i guessed it right. I see the picture and know that must be ones of micorime.
Eyes, eyebrow, nose are micorime style.
I like the scene, very nice. The plant is very nice too.
Dont like the girl/boy. I guess it is a girl cause of the short sleeves.
A bit wider chin/nose. You already have a subtle adams apple, could get a bit more.
The clothes are the main thing. Roll up the sleeves above elbow would be a thing,
and a belt. The hard shadow on the shoulder looks like he have a shirt with puff shoulder, a thing a boy should/would not wear.
What about making a big bad 240 pound biker guy, bold, bad healed broken nose, unshaven.
In the same scene, reading a book
