The lineart is ok. Kind of strange on the right leg (our right). The block thing above the left shoulder has a few weird angles and doesn't feel straight.
But I think the main error, is the drab color scheme. I think if you had a little more saturation, with the blues and reds being more saturated, things would have "popped", more, and generally been nicer to look at.
I think you could have used a few less colors, too (especually with your reds).
