Note, I havent used any of these packs, just suggesting a few artists that you may like. I`m sure most people would recommend Gabe, he has a bazillion sets, so if you want something he probably has a set for it. He has some complete maps and tiles for you to create your own. <a href="https://marketplace.roll20.net/browse/search?keywo" rel="nofollow">https://marketplace.roll20.net/browse/search?keywo</a>... Personally I love Brass Badger Art, she also has some tokens set and modern if you are also interested in that <a href="https://marketplace.roll20.net/browse/search?keywo" rel="nofollow">https://marketplace.roll20.net/browse/search?keywo</a>... Meditating Munky has a lot of sets also, his Endless Dungeon sets are modular (complete empty rooms of different sizes plus props), so they are easy to use for map building. <a href="https://marketplace.roll20.net/browse/search?keywo" rel="nofollow">https://marketplace.roll20.net/browse/search?keywo</a>... If you want a retro/pixel look for your game, you can look for Zeshio, he has some cool tokens and top-down map tiles <a href="https://marketplace.roll20.net/browse/search/?keyw" rel="nofollow">https://marketplace.roll20.net/browse/search/?keyw</a>... On my case, I also do Pixel art packs, I also did an Isometric one, which is a bit more complex but looks really good (tho I only have one set of that so far) <a href="https://marketplace.roll20.net/browse/search/?keyw" rel="nofollow">https://marketplace.roll20.net/browse/search/?keyw</a>... For some of these (I know that for Zeshio and my packs it works perfectly) I recommend a program called Tiled, its a free program to create game maps (similar to RPG Maker) where you load the tiles you have, set up the size of each square (for example in my case, each square is 136x136), then you make the map with simple controls and layers, when you are done, you export it as a single PNG file and upload it to Roll20 (this way you only have 1 picture for the entire map so it should load a lot faster).
