well you asked for brutal critique so I will say one thing: do more studies!!! you obviously have skill, I really like "see no evil" and the portrait of Paul - he's instantly recognizable and well drawn. But I think you're just rushing things and not taking time to give some love to your art. You have imagination but your imaginative pieces show a lack of studies and basics, making them sorta lack some kind of cohesive structure to make them believable.
so yeah: more studies (life drawing, photo reference, etc), and more love for what you're drawing
