Go large! Go messy (but bare feet was not a great move 🤣) Some of this is ugly but I don't mind that. In fact, at this stage of you can come back and know which parts you want to cover that takes you into the next step.
You can do more than just cover over though - maybe it needs just to be darker or more light or some texture, or the shapes are too small. Really there are so many possibilities with any painting, it's just a question of deciding where you want to take it - and usually those ideas come from within the painting itself. #justbegin
