Here's some previews of the pencil version for Swamp Thing issue 19 and a concept drawing. Issue 19 is a massive gatefold cover featuring Scarecrow fighting Swamp Thing. I'm only showing some pencil details and part of the cover in this post.
Keep an eye out for the full and very detailed ink cover which will be shown soon!
This is from the Preview version for issue 19, which I colored too. (final version is inked)
