I would love to see more art packs like this Wall Set available on the marketplace. I build a lot of my Roll20 encounter scenes from scratch and having wall tiles with transparent backgrounds is a big help. Other variations of stone walls (natural rock, cobblestone, brick, etc) would be great, as would be different types of wooden walls (timber frame and log, for example). Another great art pack would be a series of road tiles with transparent backgrounds. All the way from foot paths up to cobblestone-paved city streets. I know there are already lots of road tiles available in the Roll20 Marketplace, but almost all of them come with the background already in place. And the background rarely matches the look I'm going for. Having sets of road tiles with a transparent background would let me put down my own background tiles and then lay the road tiles on top of it, in the exact pattern I want. While I'm at it, I may as well ask for transparent background water tiles too. All the way from small stream to raging river. With the proper semi-transparent shadowing along the edge of these water tiles, they could be laid on top of a normal background tile and made to look like a water course flowing through a carved-out channel. If a Roll20 artist were to produce sets like these for the Marketplace, I for one would certainly purchase them.
