Self-Portrait-ness

I've never enjoyed drawing myself, especially from a mirror straight to the paper. I've been ok doing self-portaits from a pic of myself but until last semester I really didn't have much experience with it in person.
But as always in these classes I have to do things I'm not used to and that I'm not very good at. But today we did another self portrait from a mirror during class and I was actually pretty happy with how it turned out. So I decided to get a pic of each one I've done since I started last semester. This isn't ALL of them but a couple I either don't have access to or they're so light that they won't come out as anything if i took a pic of them.
Anyway so here there are, starting from last semester....
(i look kind of awkward...kinda pointy faced or something....)
(My nose was too long the first time and then I made it too short and then I got it in about the right place but it ended up pointy or something again...oh and my lips have problems of their own...)
(This was this semester...like two weeks ago. We won't even start on the problems in this one...it was embarrasing-oh and did I mention --FRRREEAAKY hair. I didn't even turn it in. I did another one right after that i'm super happy about but my Professor still has it)
(This one.....I don't know. It has its good parts but...something is just...Off..the size of my bottom lip and the shape of my forehead or something. lol.) (k, now this was today...like an hour ago. I'm really happy with it. As usual it has a problem or two but i think they're alot more minor problems than the other ones. I feel like I've improved, so i'm happy! ) (oh and haha i wasn't even wearing earrings today but I got done early and wanted something to do....so i added them in)
