First Freelance Logo Design

Wowsa, first dribbble. So I've been working on some logo design, which is a new thing for me. I usually work on projects where a logo has already been provided. This is one of four ideas. I really like the typography I've chosen (which is chalkboard) but I'm worried I've gone too basic with the concept. I did a load of research on logo design and I wanted to keep it clean and fun. Comment/suggestions very welcome.

Cheers
