Here's my attempt.
As an aside, this was done in new journal, a 5.5" x 5.5" Earth Care Sketch Book by Grandluxe, that I bought last week. I like it. The only drawback I've seen so far is that there is nothing in the description that says archival or acid-free. There's some shadowing show-through with heavy Pitt pen, but no bleed through.
