Tutoring Business - The busy bunny needs help with school work and that is why the bunny looks so upset. Audience would be students and parents. Logo would be used to get people's attention about how a student struggling with school can get really upset and how the tutoring can help turn that frown upside down.
Counseling Therapist - Pediatric Care - Most little children do not enjoy going to the doctors, so if I put a smile on the bunny the doctors might seem more welcoming. Also a counseling center or guidance group that helps with depression, anxiety etc. could use the sad bunny logo. To show that this center can help make you not feel like the sad bunny anymore. Audience is anyone who needs a therapist and any child who needs to go to the doctors.
Humane Society - The bunny looks all sad and frowning, so this could grab the soft, appathetic side of the audience. The audience can be anyone at all, it helps if they love animals haha. The logo would draw people in by the fact that the bunny is sad and needs a home. To promote that people should adopt animals and give them a home as their pets.
