Help with hard edges in drawing?

[Jennifer Geary]

Hi all!

Well, I have been practicing my drawing a bit more, and am trying to learn to soften my edges a bit. I think in the below drawing, I still need to do just that. I use Ebony pencils for my drawings...on illustration board. If you can give me some pointers on this, I would appreciate it! I am trying to master pencil drawing, (my husband loves those the best), and I know I am in the right place to get some help! Thanks in advance! I will post a detail of Grace's head for you as well.
