Hey @edgarsart another awesome piece of art, and I like the videos of you drawing.
If i could make a suggesting on improving the videos -
I think it would be good if you did a voice-over of the video telling us what you are doing, and why etc. What bits were hard or tricky, what bits were fun etc.
This would be a bit more instructional than just showing the pencil doing all the work. And it would let us get to know you a little better :-)
But that is up to you. either way, thanks for sharing your lovely works of art with us.
