Firstly it’s a great drawing, now I see the light source is coming from below but on the nose you’ve put light on a plane of the nose which points upwards . I’d say do some studies of the Asaro head to figure out what planes of the face, looking what directions. For the mood part I’d say add some highlights, a darker value if you want, shadows in the hair for sure and right now I don’t know if this is just a choice but the eyes look lifeless so I’d add a pupil a dark and a light too. In summary, learn the Asaro head,add shadows to the hair and to some other things such as the leaves and give the eyes some life. Sorry I couldn’t draw anything I’m on my phone. In terms of drawing your much better than me tho tbh it looks great | Artwod Feedback
