For your first project it's a great place to start - you have to be comfortable with what you are doing.
It does seem you've done a lot of work to this one already then so that next step of making the shape yourself won't be that big of one to take.
You can make your own template quite simply with some plywood or MDF and a jigsaw, a file and some sandpaper.
If you are after a standard strat/tele body etc to start from, Simo sells great accurate templates. I have some myself ready for my Tele project. It saves you messing about with them yourself if you'd rather get straight onto making the guitar itself.
All in all, you've done a great job with this project - lets see another one then!
