The upper sketch is copy of 2010 watercolor of F.M.Marrouch (here) done with the only brush and two colors, ultramarine blue and burnt sienna.
In 2010 I was impressed by this painting and had no idea how it was executed. Now, 3 years later, seems like I know)))
Sketch below is inspired by photo, again of 2010, and I have no clue about the author.
And at last I feel fed up with copying of masters' works for the time being.
