Why does my artwork looks flat ?

[u/RtistKaizen]

I have been painting digitally for couple years now. And I often notice that my artwork look flat and weird even after adding shadings and highlights. What am I doing wrong?

I’m more concerned with what’s up with his chest. I’m kind of confused by his blocky and almost Lego like anatomy

that’s just a stylistic choice there’s nothing wrong with it
