Ooka and Yumi are playing an enterplay mlp card game.
Ooka & Yumi characters belong to fushigiooka
Basically Yumi is being super serious (or enthusiastic) while Ooka is simply enjoying the game and going at his own pace.
Since it is a slice-of-life setting, I decided to try out a different, cleaner/smoother drawing & coloring style. To be more "anime"-like.
I didn't make the cards or the vector for the elements of harmony. I couldn't find the source or creator of these resources either. If someone could direct me to the source/creator, I'll gladly credit them. If it is not ok to use them, I'll replace them with different playing cards.
