Male Side Profile - Improvement

Wanted to show my improvement in male faces/side profiles in the past few months.

First Pic: Made 12/2/2016 when my style was completely different. Ended up spending a lot of time on a "quick doodle". I hate his hair. Took forever and still sucks. xD

Second Pic: Made 1/31/2017 after I started coming into my new style of having a lot less lineart and going for a more realistic, less anime/cartoon look. As you can probably see, I didn't feel like attempting to draw an ear so I hid it behind his hair. Er.. Did not work. I am not very happy with this one.. especially that eye... -_-

Third Pic: Finished today, 3/12/2017. I tried REALLY hard to make this one look right. Searched up a ton of pics for reference and ended up changing his whole face shape halfway through, but (for once) I'm very happy with how he turned out.
