Across all your designs so far I have liked your style of drawing Kitty.
#67 is the leader among your designs so far. The direction you went with Monster is definitely more on track. I think the tail becoming the heart around Monsters face is creative, but distracting. I'd like to see this one with a more normal tail.
#60 #60 Layout is good but Monster needs to be much larger in proportion to Kitty.
#97 is your best yet. The lines of the hand/arm holding Kitty look a little strange to me. Maybe try a different shape there? I'll try to think of more specific feedback but I like this one a lot. Very simple but has great personality and fits the brand image.
You may notice that I have put some of your designs in the Non-Interesting section. This is to help me organize and focus on my favorite versions of each logo. Please do not delete submissions marked as Non-Interesting, I would still like to see them.
Could you please also prepare a colored version on #97 Kitty should be orange. Monster can be purple, green or blue. Thanks!!
