We like very much your entry 27. The mascot is really great and you found a good idea. However, can you try to design the same mascot but without the sting, we affraid that it would be a llitle too much agressiv in a small logo. Perhaps a hand on the hip for example or whatever you think is great ;-)
Another remark : if the logo is on a visiting card, for instance, we will see much more the mascot than the name of the brand, won't we ? Can you try to increase the name of the brand or reduce the mascot or... if you have another solution ? ;-)
