Double Team - Fake Card Illustration

[Madzia]

Characters and background is so sweet, great job with it. The only thing is this object at the center. I totally don't understand what is it. Is it trash can? or an armchair with villain hidden in shadows

I dunno I can see it with my imagination. It's probably because the characters eyes are directed to center and I can't accept they are looking on boring trashcan. It have to be something more!! xD
