When I first visit your site, just viewing the header, I don't get the impression I'm at a tutorial site. I would choose a different color palette, as the current one seems to be a bit bland or dull. The actual post area looks nice and is formatted well, but the white and tan again I feel don't mesh well -- too plain. Here's an example of a site that really screams tuts/design when you visit it

Granted, it is Envato , I think you should try adding more color in your header, maybe some soft gradients and 1px strokes to spice things up.

Good luck
