Very very good! I like ink drawings and when I look at the masterpieces, the motto there seems to be "less is more". To achieve the greatest expression with only sparingly used brush strokes, a real art. Your work reminds me a little of that and also that only black ink was used. The sword hilt at the top would have needed less detail, I think, a hint of artistic ornamentation would have been fine. But I'm criticising at a high level, I'm enthusiastic about your drawing and also the attitude of the character. There is something witty about him, a serenity.
