Your nametag says you are not yet a marketplace creator so, have you begun the application process? An application is a long process that will keep you tied to your emails on a weekly basis with roll20 for 1-2 months over about 6 emails. I believe you will be a yes if you are indeed waiting to become a vendor. The two samples indicate that you have talent and that your work is clean and precise, suited for all manner of product applications (like tokens, cards, UI, ect). Based upon what I've seen available in the marketplace this style will fit alongside a growing "trend of products" (people who purchase other creators works may discover your art and add it to a collection, I've seen similar work). Experiments can fail but it is worth trying them. Make what interests you and just bear in mind that the value for your time put into these products can be a slow return over the course of years. The variable affecting your return can be the quantity of products you make available over that time which can have a snowballing effect through page visibility and the sheer eldritch terror that is advertising. Twitter + #roll20 = the void
