The lights in this photo are terrible, they are completely blown out.
This is my start, this took about 5 minutes. You can see how very loose it is.
After 30 minutes I have begun improving the drawings accuracy and establishing a bit of the half tones along with the lights and darks.
At the very end I used a large brush to fade out the whole drawing. When I work on it again I will have an accurate base to work with but it won’t have any hard edges so it will be easy to work into.
