This is lovely. I appreciate how intelligently you used the various media you worked with to bring out different textures, and so many different kinds of lines.
Using heavier blacker lines in outlining the neck and face, drew attention to your delicate and rosy handling of the form which I thought worked very well. And in contrast to the quiet grace of the form- there's a springy curly energy in the hair which gives the piece some lovely and much needed energy.
And speaking of lines- I quite appreciated your elegant and elongated use of line- there's a little bit of a Modigliani-esque feeling to the work as a whole which I quite like, Modigliani being one of my favorite artists.
The only part of the piece which does not quite work for me, if I might be so bold, is the emphasis on the eyelashes. They seem to dominate the face a little too much for me- and distract from the the shape and delicate modelling of the eyes.
