Adobe Photoshop CS2
Before I discovered Adobe Illustrator, I experimented a lot with Adobe Photoshop pentool. It's more limited but also a good option for simple projects. I started designing Yoyo and Cici (a couple of cute monkeys) dressed up avatars to use them on the internet. People started asking me to customize the monkeys for them, so I did. I enjoyed that because cute japanese aesthetic is one of my favourites.
