1-UP Mushroom: my first solo surfacing model

so I've been daveling in surfacing recently to expand my brain and try new stuff.  I've been going through Perez's camaro tutorial, reading Lombard's blog on surfacing, going through many other models/presentations/references/tutorials found here on the forum. (soap,ipods,iphones,razors,etc)

so after getting many general ideas on different techniques I've decided to try my own hand at something I haven't seen done before and see how it goes.  here's the result.

I've also attached the model.  I know there are some small curvature issues on the back and front down the centerline, but what do you want?  Any comments/critiques welcome.  I'm going to do a couple fun things and do some renders in the future.
