Inspired by Scott Flanders' art I tried doing graphic style illustration, however the shading and some of the details don't feel right...
Would greatly appreciate some feedback
Here are the the finished piece, the blockout, the cleaned sketch and the initial sketch

I really like the gesture and the "vibe" here, I think it has a nice sense of drama.
Two things that jump out at me though are the head and mouth "cowl" seem pretty big for ole Swampy. I think making that a bit smaller might help the general profile.
The other thing is that while I do like your use of darks, I think this really needs some highlights to make it really pop. Maybe create a new layer and experiment with some highlights so you can preserve the vibe, but give it more depth.
