Well..I'm a fan of 'Don't step up to the plate unless you plan to hit a homerun.'
However Since you just started modelling a few days ago this is an encouraging start. Keep trying and do remember Texture is more then half the equation...a low poly count/bad modelling can be completely overlooked if the texture is good. I'm not calling you modelling bad, its a good start for such a short time. I'm just pointing something out that can save you some trouble later on. It's worked for my models. I've spent more time working with the textures then I have modelling thing.
So keep it up and try try!
