Greetings, JV Aubineau, welcome to the forum.
A few observations:
- I like the thinking behind the three horizontal ovals, but this idea might work better if they were not all the same size.
- There is a possibility here for starting in the middle with the A which might work out nicely - the lower JVD example below suggests how this might be arranged.
- One nice finish for a V (or W) is to wrap the tail round into a huge oval. That way you could perhaps loop it over the top of the A and right back underneath to start the lead in for the J. This will take some serious whole arm movement skills!
Whenever I see a nice signature combination I take a photo or screenshot and add it to a bulging folder of examples. (Strange how often CPZ and PZB turn up ...)
It's a fascinating aspect of Ornamental Penmanship, and very demanding in terms of design as well as execution. No doubt the stories about Madarasz and Courtney just swinging these things off are true, but for ordinary mortals coming up with a really good one will probably take hundreds of sketches of dozens of variations. I don't have the technique to attempt these, and probably never will - so I admire your dedication in pursuing this.
I don't have a JVA, but these JVDs by Courtney and a JWB by Bloser might give you some alternative ideas to play about with.
