/ic/ - Artwork/Critique

thought id ask to get a reality check on my progress. 3 months ago the heads on the left took me about 30 minutes each to draw, I decided to throw together some rough ones to see how I compare now. these took me 15-20 minutes each. >>4402374 is what i got when i wanted to do a more in depth one.

When i posted these back in december someone told me It looked like i was just drawing an outline and adding the features inside, is that still the case? im trying to show the form of the face more. My rendering also leaves a lot to be desired. I havent even looked at how to draw hair.
