After getting the Cuda blocked out and primed,  I jumped back on the 507 and got the rest of the foam sculpted.  A couple areas I need to go back over some more since I'm not happy with the lines,  but overall,  the shape is there!  
Up next will be the bodywork.  I'm thinking a may glass this with one layer just to hold everything together,  then start the bodywork on top of that.  
More to come as it takes shape!
 
Cheers
