I’ve created this youtube video which you can’t missed out because this is a very easy approach for beginner to paint water-colour post.
The main tips is leave space between petal and keep in C shape stroke (no long stroke! pedal will be big and thick but never long). If you want long pedal, please keep it thin and maintain in curl shape.
You can see my below picture.You can treat it as 1 painting style for number 2,3 and 4. So 1 technique can have 3 different roses in your drawing. Pls try and tag me along so I know it’s your work.
