Hey thanks for the kind words on the art I've passed them onto the artist :)
In terms of progression I had thoughts of using the money you get from the art so it's a trade off of meeting the goal vs making the goal easier.
As for the actual upgrades would of any of the following been useful?
- Different brush sizes
- Different brush heads e.g square
- Different ways to compare the art? e.g a tool to overlap your art with the original
- A preview of the accuracy before placing the art?
Let me know if you had others things in mind :)
