Sculpting a cartoon grandma

This is my first practice sculpt while following a cgcookie course( In the tutorial they match the reference from angle but I felt that might be too challenging for me, so I did a symmetric sculpt. I was also wondering if there was anything i was missing out on if i didn’t sculpt the match the reference.

I don’t have a side view of the character so most of my attention went to the mouth, chin, eye sockets, and ears. The sculpt looks very rough from the side. Still haven’t finished the tutorial yet so watching the rest will probably help with the pit falls I have. Having a hard time forming the eyelid around the eye and flattening the lips.
