There’s one thing I warmly advice you (as it has taken me a couple of years to find out): Watch the right instructionvideo’s (as there is many of tabletop quality videos to find but I guess you weren’t aiming for that) Painting Buddha (still!) has some superb ones online for instance.
If possible try to attend workshops from DIFFERENT renowned painters because you want to learn that there’s more than just one way to apply paint and by doing so you’ll find out what will suit you best in different circumstances.
And last but not least, after a while, try to find some interest in colour theory, you won’t paint better but it will help you to create balance and atmosphere. Happy painting :)
Keep in painting bud the more models that pass through your hands the better you’ll get!!!
