FWIW, my comment was not a critique, just an observation. Good soldering technique only comes with practise (good equipment helps as Andy pointed out).I will add copper tape near the control cavity screws, great suggestion, and yes most definitely I need to work on my soldering skills!
I was a bit ashamed of uploading that picture, but the feedback I have received definitely pushes me to do better the next time. Thank you!
To me, soldering is a bit like spray painting a finish. It's something that takes a lot more time to get good at than it takes to do on a single guitar project. And unfortunately not something we (myself included) invest hours and hours doing and redoing just for the sake of self improvement. Especially with spray painting (gun or rattle can) , it gets expensive just blasting paint on scrap timber or cardboard!
