I've been wanting to do a fan art mashup of the Pines Twins (Dipper and Mabel) and CatDog (Probably because I haven't seen any other mashups of these two sets of twins, I don't know WHY 😄). I've been pairing up Dipper and Cat as a duo, because their similarities (to me, at least) are nostalgically uncanny:
1) Both are the more 'serious' siblings
2) Both have endured ridicule
3) Both have shown their intelligent sides
4) While both do get irritated at their siblings shenanigans (Mabel and Dog, respectively), both still love their siblings with all their heart, and will always be there for them
5) Both have their distinguishable anxiety lines underneath their eyes (idk if that's what you call them tbh)
Anyway, the end result was awesome! I depicted them hugging each other tightly as they are faced by an impending force to be reckoned with.
