Hello there! Thank you for taking your time on typing such a long comment, i will try my best to respond to it!
I understand if someone does not find Dr.rabbit endearing at first, many people sometimes asked me why he is there, because back then i used to paint scenery that has no character nor context and it just felt a bit dull. So i re-iintroduce Dr.rabbit from my old painting and his episodic story which each painting bringing him to a new area to discover.
Originally Dr.rabbit's purpose is to be a scale for the sceneries he's in XD so you're right on that. He still is right now. I want to make him as someone that can easily be related to the viewer and become their surrogate to the situation in the painting. I want to make it as if the viewer is travelling along with him and reading along his adventures on the journal that he's written on. Also making their own thoughts and interpretation to what happened to the world, who is Dr.rabbit, what is he looking for or his purpose etc. A lot of these tales are shrouded in mystery if you look into it closely haha.
Overall i really appreciate your comment, thank you! And i hope you stick around for his future adventures
