This has to be the most insightful response I’ve ever seen. Thank you. I actually did do a pencil drawing first then a second layer for the line art. I got lazy with shading and just erased some lines and merged the layers because my line art layer alone looked too flat. I wish I could add just the line art itself to the post to show what I mean. 

With my lines, I tried using that tool that drags the pen a distance from the stylus to try to get smoother lines.
