Hello everyone! I am new in this beautiful community and i can't define myself as an artist because i am really a beginner. Never attended schools or courses on how to paint and i am just in panic because someone saw my sketches and asked me to make a professional portrait for their children. I bought watercolours but i have no idea if i am using them correctly 😅 and as i alredy made a mistake in using lot of black paint to make shades i was just asking if adding layers of colours can i adjust the black. Any tip on making portrait or using watercolours is accepted . Thaaanks a lot!
