Gimmie some advice on stuff, i feel like i'm getting better

if you want my honest opinion, there's only about 5 fucking people
in the toribash community who can shade correctly. you sir, are not one of them, unless, of course,
you have like 5 lightsources, which makes no sense.
the way that only the tops of the letters are glowing orange is very unattractive...
just my opinion though. 6/10

Uh, Okay, My shading isn't the best anyway, Any tips for shading?

Just pretend there is the sun on one side of the drawing, and highlight the spots where it hits

For correct shading on the bomb, rotate this clockwise 90degrees.

Or just learn the fundamentals of shading.
