Well here I go again. I think it's all the years of teaching that make me critical, but helpful I hope. So here's my take on it; first of all, obviously GREAT work. My one bit of advice though is the same thing I used to tell an old student of mine that loved to work in pen and ink. If you first shade the areas out in bigger sections so the shape and depth, of the head in this case, and all the features are in, in your case with a finer point or lighter touch to keep it soft, and then add all the details later, you will find yourself not having such issues as you are experiencing. The skin of that women is as old and crackly as you made it. However, since you created that surface texture on a white piece of paper it is messing with your overall vision. Pick a small section of the face, and on another piece of paper try this out, shade and shape the object first, nose cheek, whatever, then add the hairs and skin cracks, etc. I hope this works for you. Marsha Levine, who is still in the pen and ink art business 20 years later, my student, entered a competition after mastering this technique and I promise you she walked away with first prize. She gave me the artwork with the ribbon on it afterwards. I wish such luck for you. Great work so far.
