ohh you threadomancer
how much time it takes to learn to paint: depends on the quality you want. For really basic things a weekenf workshop with a good teacher is enough. Even for display pieces it can take as few as a few months depending on how much you practice and if you have a good teacher to turn to. Imho with 12-16 hours painting/day + good teacher you can get really good within 2 months, BUT that much hours put in can burn you out, so it is a risk.
BTP: wow, I'm surprised they still exist... and after seeing pics of their work they should NOT do painting classes. It's like someone blind guiding others. Also I read horror stories about how they handle the painters and I have to say: be glad they didn't take you, you dodged the bullet.
Advice: you do NOT need companies to teach you, you can learn on your own. Even having a teacher only speeds up the process not mandatory.
Read / watch tutorials and practice a LOT with the goal of having each mini better up to your preferred quality.
What to watch/read/do (some suggestions):
- YT WarhammerTV (
https://www.youtube.com/user/GamesWorkshopWNT ), mostly TTQ/gaming level
- YT Ghoul's videos are good (
https://www.youtube.com/user/MiniGhool ), videos are mostly intermediate level
- YT Painting Buddha are really good (
https://www.youtube.com/user/paintingbuddha ), intermediate to high , They are not anymore, but Ben continued the videos on Parteon
- miniaturementor.com's videos, some are quite nice, some not.
- massivevoodoo.blogspot.com , great articles
- figurepaintermagazine, for about 50gpb you can have all the issues released, each issue has 1-2 nice tutorials and a lot of other articles
- Angel Giraldez books are ok-ish
- Scale75 books are ok-ish
- painting workshops if you have the chance. For example Jarhead's beginner WS in germany (sometimes other eu countries) is great. In 2 days you learn more than in a year or two on your own.
- trying to join a local group who paint
