Mariano, that is awesome!!! I agree with Jean, it looks like a photo. Only a good eye can pick up on the minute, almost imperceptible little things that differentiate the sketch from a photo.

Nice sketch marianogj! Can you tell shortly how you have processed the original sketch? Is that only a invert image or have you done also something else?

hello i_sairanen
Excuse my use of language. Is google translated from Spanish.
Process:
1, Original image reversed.
2 º I cleared the bottom of the sketch with brightness levels.
3 º I have highlighted the stars using the white brush.
The sketch takes only these three processes.

Thanks! I will renew my homepages and update the sketches to reverse colours. Now they have white background. Completely black background doesn't see as realistic as background in your sketch.
