Cheers for the comments.
I have to say in terms of the body I cannot see anything that will change before it gets turned to wood. It's been 3 days since I did the CAD and I have say I myself that I still look at it and think - it looks right! The design actually came from a sketch what I did sitting in the car waiting for the supermarket open as I'd arrived at the place early. It's had some refinement in CAD but after leaving it and looking at it fresh eyes each day it still looks exactly the pointy agressive type of look I was after. The main difference in the original and the CAD is that the front top curve was less pronounced and lower - however done to scale I couldn't get it looking 'good' so redid it numerous times until I was happy.
As for the originality of the 3+3 headstock . . well it was produced in CAD purely based on the curve of the back of the guitar and then selective position of the curve points on part for the connecting sides. So in that respect it's as original as it could be - if it's similar to another 3+3 around then maybe it is, no matter how you try it's difficult to be original in such a small space but it certainly isn't based on any design in particular.
Dadovfor - Cheers for suggestion but in terms of that headstock the excess pointy bit on the bottom doesn't appeal, although I did play around with a curved top like that but couldn't get it looking anything like I envisaged in my head.
As for the last headstock - I do like it .. .. but I also did a pointier version which looks like this:
(I know it needs lengthening slightly to accomodate the tuners but it that's just a tweak that could be easily made)
So round the tip or not round the tip . . . that is the question!
Just for ease of comparison as this post has gone on the 2nd page:
