I drew these in the Colors! 3D app for the 3DS. I drew a base and made 5 copies, then edited each copy of the base into 1 of the 5 frogs currently in my town. After that, I imported them to my computer, opened them in GIMP and cropped out the extra room + made the background transparent. Then I put all 5 of them in 1 image.
They're just quick doodles - I don't think it even took me more than half an hour to do all 5. But still, I'm proud of them.
And haha, n'aw! They just had a really simple design. All I really had to do was draw a few lines, pick a color and fill them in. The fact that I used the base I made for all 5 of them sped it along a lot though. I'm sure it'd taken me much longer if I hadn't.
