Like #16 - #15 & #14 - the heart shape is too simple for my liking. However you are on the right track. Still would like to see some more variations of the heart. Thanks!
Client likes the simplicity and overall look of #17 best. If you read the latest comments, client would like a hint of Harvard, Oxford, Yale type feel to their logo. Adding the slightest hint of their logos to this one would be ideal. Let me know if you have any questions. Thanks
