For the first image I got inspired by Hanafuda koi koi, is a Japanese card game for two people. More info here! These cards are really pretty and the game looks so interesting, it’s worth a shot! This was made with Pixel art maker.
The second one is Togepi! I wanted to do a cute and easy character so here he is! The final resolution is so bad, I had a problem with the size of the image so I made an screenshot, that’s why you can see the frames, sorry. This was made on Pyxel Edit.
