I Just Cannot Draw Goddamn

So I do like to draw, doesn't mean I am very good at it. But since I'm at Uni, i'm drawing more than usual.
Now I know the title is "I Cannot Draw" Like I know I can draw, obviously. But man I am envious of the people that can actually properly draw. All I can do a sketches.

Newest artwork is in the latest chapters, you don't need to look at the first chapters because that art is old now.
