Brush pen study after Henrik Rosenborg – Magnus

Hi again, here is a fantasy art study I did with ink brush pen over mechanical pencil on sketchbook paper.

Happy about any advice when it comes to improving line drawing (this kind of ink drawings are colored digitally when they are done). I remember that you have adviced that i study Raphael for line art practice, is there any other artist – old or new – that you think would be especially beneficial for my ink drawing technique to draw studies from? 

Best regards /Magnus
