ummm, sorry it's late, and this question seems to be able to be taken more than 1 way.
I mean it looks like you drew the picture on paper and then either took a pic and colored it, or maybe you intentionally blurred it since there's a white space around the lines.
??
It seems like you made your lines that way on purpose. Or just as a result of how you're drawing them
I don't think there's anything wrong with it. It's just it's not what I expect. Mostly I think because it's not how I do it. I like your drawings. The harder to define lines make your drawings feel softer. Like they'd be physically softer if I were to touch them.
I guess I'm saying, the line art looks good as is,I wonder if going for that or if it's how it turns out without you intending it to look that way.
Ooooooo
