Looking at the minimalist picture (driflooneliness haha), my first thought is that it reminds me of winnie-the-pooh (I suspect that this is because of pikachu's very round belly and the yellow coloring). I think this could contribute to the childish mood Kadew mentioned. Anyway, it's great! I especially like the "fuzzy" coloring, it just seems to fit with drifloon.
