Great help, lots of great tips. I see that after you take off the tape you have little overlaps because the paint has gone under the tape. Tip: paint the edge of the tape before you start your painting with primer. Be sure to let it dry. you will have a razor-sharp finish when you take the tape off.
I don’t think so, watercolour ur darkens when you apply more layers so I’d recommend learning how to paint light with watercolour and then try to use this tutorial that way
