Thats an absolutely gorgeous piece of foamboard sculpture.
I'll have to chime in with the doubters, though as flight characteristics are concerned.
The wing looks very heavy and while it's got a pretty thick airfoil that should in theory create a lot of lift I think the rearward taper is too steep to allow theair to flow off of it without a lot of turbulence. Also, since you've got almost no apreciable self-righting with a mid-wing setup and no dihedral you might want to have a thicker profile or even undercamber on the outboard wing panels kinda like tche cessna corvals or, indeed the flite test planes.
The head is a great bit of sculpture and it makes the whole thinng come alive. It will also create a lot of drag as well, though and that's not something you want in front of your wing since it will counteract your stabilizer and might make your plane lose yaw stability.
The tail has been mentioned before and while I said you'll need a big tail to counteract the drag of the head I feel the airfoil you chose will cause problems along the line because it will create lift far behind your wing. That lift will push your nose down and that downward pressure will only increase as you gain speed. A profiled tail might help with stability but you should probably choose a symmetricall airfoil so you have neutral lift in the back.
Of course I'm not a professional aeronautical engineer, just a member of the armchair physics brigade. I probably should just shut up until I got at least one of my pipe dream designs in the air...
