I also have a MAAAAAAAAAAAAAAAAAAAAAAAAAAASSIVE library of maps. Not that random shit you can Google, I mean the high-quality shit you have to buy. However, I do have an art style preference and the cartoony shit isn't for me. if you Google Heroic Maps, Beneos Battlemaps, Dynamic Dungeons, and Advanced Battlemaps you'll get an idea of what I have. I've been a patron of 15 map-makers every month for years now and the amount of shit I have is borderline retarded. I had to buy another SSD to store the shit.
Music, ambient sound, and effects as well, but I'm not getting in to brokering that shit. PDFs and maps is all I'm willing to share with you fuckers.
