"The ones that make it complicated, Never get congratulated"
I've been thinking a lot about overarching ideals in painting and this lyric from Kid Cudi really spoke to me. For painting, there's plenty of rabbit holes to go down in terms of technique, but I've only found them all to be detrimental. The best technique is the simplest.
Personally, I use a full palette ebauche applied in a frottis (rubbing) manner. This is something I've applied from Bouguereau. There's a lot more to painting, obviously, in terms of colors, brushes and mediums, but what I'm saying is that the physical application of paint is all that matters and must be direct as possible. There's no fancy technique that you can hide behind.
Go out there and apply paint directly and don't make it complicated.
