Hey! Sorry for the late reply, my career has kept me busy. ^^
That's a very clever suggestion for downtime activity. Class-based expanded downtime options would go a long way towards strengthening class identity, and I've sometimes had players desire more structure or solid options for fantastical downtime. A joint activity that all players can take part in and benefit from could make for a fun crew ability, (Like a tavern crawl)
It's very kind of you to offer your art skills! I like your style and I think I will commission some art from you at some point if you have time. As soon as I am less busy with work I will start spending more time on art.
