I picked the second one. For the first one, I feel like the idea might be a bit too simple in that we'd get typical scenarios like the MC having moral conflicts about doing some things. I feel like making it really striking would be difficult. But I could also see it as a comedy which could be very fun. If there's a fun dynamic between the hero and villain it could be interesting.
I'm a bit confused by the image attached to it. I'm assuming the superhuman is the bear?
The second one could be more appealing as long as the art and world building are fantastic. I like how the concept art is greyscale with some mute tones, maybe it could use a bit more since the drawing has just the character's lips painted not grey.
