First dust shoe design

Well after playing with vcarve pro for a little bit, I can up with this simple design for a dust shoe. After three different cuts, I think I got it right. (or close to it) What do the pros think? I'm still learning the software portion of this, so any insight is welcomed. I tried drawing it up in AutoCad 2013, but that is still out of my grasp.

Thanks,
Justin
