Copping Mignola's Style - First Crack

Here is the first 'official' piece of art I've created for Saga of the Splintered Realm. I tried to emulate some of Mike Mignola's techniques - with uneven results, to be honest. I like it, but I don't love it. I don't know how he does what he does yet, but I'm going to keep plugging away at it. I just can't run all of those black areas together without the whole thing losing its shape. He is able to run multiple black areas together and you never lose each individual piece - your brain is able to fill in the line work. I either can't get it to do it, or I'm not confident enough to just go for it. You can decide for yourself...
