Not a bad website.
- The background image adds a lot - nice job there
- You added some color and branding
- Music samples
- Clear pricing
- Twitter feed makes the site look active
What it could use:
- A logo
- Pictures of what you do
- Pictures of you
- Twitter feed looks slightly stale
- Site feels a little dark
- Site could be slightly easier to read
It's good that you have a site to center your work and add credibility. It just needs to feel a little more like you, like the person behind it.
How new is the site? Have you gotten any sales yet?
