Don’t get me wrong, your photos aren’t awful but they could use a little polish. Very few of the photos you have on there are photos that people would actually pay for though which suggests to me you probably need more experience with a variety of subjects (i.e. people as flowers/dogs/squirrels won’t pay you for photos).
I don’t think you are ready to be charging yet based on this. The photos aren’t really the problem although you have some major depth of field issues but the spread just isn’t there. Give yourself a bit more time and build up the necessary experience before committing to this as a business. Taking good photos is only a minor part of being a self employed photographer after all. With the photos you have on there I’d be surprised if you couldn’t get some second shooter jobs with local pros for both studio or weddings.
