(( OOC: Oh man, this is a hard one as I’ve been painting a long time and have just slowly learnt how best to work with the medium. I will say though that watching artists on YouTube and instagram can be a useful way of picking up on techniques!
My favourite watercolour artists on those platforms are kelogsloops, Danica Sills and Sara Tepes, so they’re a good place to start! However, they all have very different styles and techniques, as is often the case with watercolour. The best advice I can give you is to experiment as much as you can, make as much bad art as you can and slowly figure out what works for you. Good luck! ))
