Robots got feelings too'? They look in great relief ! Could be bunny/mouse-robot and cat, cat saying: "Cant hunt you anymore... " "... you can still chase after me !" "So true...! " And both laugh&cry in great relief ! - Wonder what great powers turned the mouse into a Robot,lets call imagination !
You know what I love about this? The robot really looks like it could be a concept design for a serious and dramatic sci-fi video game. It actually looks like a threatening killing machine. But you added the twist of including a cartoony cat that looks like it could be from a Nickelodeon cartoon which then gives the whole picture a humorous vibe. There's quite a cool contrast there.
This is why I love randomness in pictures. Great job, the two styles you used in this work together very well too!
