This sucks D:
Just how I do heads/position features on the face. (ignore my Hagi-like end result, I was watching Blood+ earlier today! D8 )
I added some different eye styles for you...
The nose, on a fullview, has the same kind of 'M' shape as the mouth curvature does. On some people, this is not as noticeable as on others, since they may not have full lips, or they may have a bulbous nose. I dunno. lmfao.
But yeah. I can't stress how important it is to look at OTHER tutorials, AND artwork, and ESPECIALLY draw from real life, preferably NOT photographs, but an actual person. I know it's hard to get someone to stand around for you if you're a 'beginner artist,' and it takes a bit to learn to draw fast, but do your best!
Also, don't sketch hard. I used grey and red in this to show you what changed in each 'frame.' The red is the new stuff and the grey is the old stuff.
Don't forget to experiment and play around with other styles too! D: Don't rip mine ;3; lol
