Well notbad
This was a nice drawing here kind of like a sketch I think if you colored up the hat and nothing else that would be a nice touch up on this, Lines are relatively thin save for when shading is "PROVIDED" said shading gives depth to the image and adds "PERSPECTIVE" for the viewer, Although the lightness of the lines also contribute to the profoundness of the "VISIBLE-DETAILS", The bold texture of the marks on his face make for a solemn tone, The boldness of the pointing finger is somewhat aggressive, as well the viewer is able to acknowledge being addressed by the man in the drawing.
