Hello there! Just thought I'd post this little resource. It contains some Gen 3 styled overworlds of Gen 4 and 5 trainers. Enjoy!
Hiker/Lady/Camper/Picnicker/Supernerd overworld sprites courtesy of Young-Dante on deviantART, so not everything is by me (they're free to use too don't worry)
Everything else is by me, so be sure to credit Mashirosakura when you use them!
