@jenithornhill I like the light sky and contrast with the dragon float in the second one up. I still think there's too much confusion in the camper itself, though, and unifying the values more might help with that. You've did that more in the last one, but still, set them off even more against the sky. That way the camper will read as one big silhouette, despite all the details. It may go against your lovely 1950s camper design, but I wonder for example what it would look like if you made all the white part a color of similar value to the bottom, blue green part?
I do like the frog bigger, but now that his head is in the middle of the camper confusion, the silhouette is not as clear. Having him so big also changes the focus from "a crazy family of flamingoes have a pet frog" to "this frog lives with a crazy family of flamingoes." Just make sure that's the story you want. I also just now realized that he's not out front, but that they are dragging him from behind! I wonder what happened? Did he just make a big jump and end up falling off, or was he after something?
I also just wanted to add that your drawing here is great! I love the delicacy of the line, especially in the rending and shading on all the camper items. You must have had fun designing all this and it's really worth making it read at its best!
