I think
#28 and #1 / #10 are my favorite designs. I like the compass, the palm tree, and the x marks the spot on
#28, maybe you could play with the layout and making it look less like clip art. Try making the Shagnuts larger than the travel. Keep the dotted lines inside the box. Try different styles of compasses.
On #1 / #10 try different styles of worlds.
Thank you for your work
