i dont have a subscription so i cant give a proper critique. the likeness is fantastic the eyes and nose are really delicately and finely done. when it's smaller the image looks really detailed and perfect smooth skin etc. however, when you enlarge it the image looks a bit grey and you havent done enough varying shading on the chest and around the mouth. i think it is really good, my only suggestion would be to add a bit more shading around her mouth etc. also, my other suggestion, it looks as if you've blended the shading with your finger, while this is a common suggestion and technique, my teacher told me never to do it as it results in a picture of very similar shades, so i would suggest shading with just your pencil, and only blending within one shade and a very small bit between shades because i do understand that sometimes it is necessary to blend occoasionally. but yes that's my rule of thumb, and those are my tips, i hope thats ok?
Thanks for taking the time to critique, I really appreciate it . I understand exactly what you say; this drawing's over a year old so I try not to blend with my finger anymore now (it tends to go smudgy now as I use different paper) and just use pencil
