It's 0 bleakness! 
My comic is so bright, happy, and cheerful!
Well, maybe you'll find something like rolling heads, pain, sweat and tears, skull fractures, impalement, but it looks bright and colorful! because it's only a battlefield in the broad daylight and those things are perfectly normal right there!
Maybe you'll find something like a traumatized woman, but it's not so gloomy because she smiles very brightly. 
Caution: it might give you an emotional roller-coaster, surprise, and a lot of laughs.
