Lots of cute and certainly colorful. But to paraphrase: less crowded is more. The chick and the bear don't seem to be associated with any particular product. The outer edges of "Diaper Company" seem to exceed the boundaries of its logo. "Mouse Cheese" could stand out more from its background. These would be fun presented as billboards/signs/whatever on a cartoon street and would seem more 'realistic' in that environment. [BTW I think "TM" is supposed to go at the end of the text that has been trademarked.]

It also is not clear why these animal would be associated with their logos/products. what makes a lion suitable for a diaper company, and why a worm for "industries"?

I admit I had somewhat of the same reaction as happyme27 but I convinced myself that maybe Algernon Worm, for example, was the founder of Worm Industries. And it's a lioness—which might have a greater interest in diapers than a male lion but whose use here perhaps could be lacking in political correctness.

UPDATE: A male (adult) lion, of course, would have a mane.

Nice job author! If it was me, I would have made just one. There are many good ones but my fav is lioness diaper company. Only suggestion on that would be to make the "diaper company" the same size as the box with lioness
