Is not an ink drawing, but pencil and then some color with photoshop...

Hey @Anibal Lopez Lenci! I like the “inky” aspect of your drawing. I think the pose might be a little bit ambiguous, like “what exactly is he doing: jumping? Falling? Hanging?” Consider precisely what you want the character to be doing and then try your best to draw his gesture and body expression in a way that clearly communicates that action. I also think there might be a bit too much information on the bottom left area of the composition, which makes it even harder to read the character’s pose. One idea I can think of right now would be to bring the horizon line a lot more downward, show much more of the sky and perhaps concentrate the city on the bottom area, while character remains on the upper area looks of the frame - this might help bring more attention to the character and also make his silhouette appear more vividly. Maybe even tilting his overall shape a bit more could help add more movement and dynamism to the scene. Hope this helps!
