Hello denzu,
Cheers again for your entries! I really like the new entry #20. Could you look at using different style bottles and or glasses? I think the best thing about these similar designs is the simplicity so keeping that would be critical when doing other variations.
Also i do like the font for MAB that you have chosen for entry #20. Could you further explore how it might look with the MAB to the side??
ALSO this might be a long shot but there was something about entry #1 that i liked and i couldn't get my finger on it. Initially i was unsure if that was a door in the bottle or what, so i thought maybe to personify the word 'mad' you could try by putting three bars up near the top section of the door ie like a metal asylum/ prison door.
