All the black elements of the composition are done using brushes and transfers from the APP.
The intensity of the black is so beautiful, I could not recreate that black color,
I sued the transfers and brushes they are so unique in its black intensity.
I used my watercolor technique, and also the clone technique that I like to use so much these days.
I have repeated a couple of layers with a blending mode color burn to give intensity to the color of the sketch.
I used a number of transfers from the APP remarkable on the left and right of the composition to recreate the feeling of a coat.
