Here an old chop I did a while back.
Notice the old lines one the rear door are gone. The side windows were all made in to one big one then new lines made, but not to far back. The pillar doesn't need to be enormus either. Somtimes a fat black line will do and be sure to match it on the other side if you can see through.
I like your chop.. It looks badass.
Hope the visual help ya a little..
