Edit: Looks like it is. You could go asking for feedback on one of the popular indie book forums (assuming there is such a thing).

Marketing, at its most fundamental level, is simply placing yourself where your target demographic is, and then socializing with them.

Remember: simple questions often are best answered with simple answers.

Good luck! :D
