Everything I do is unfinished

[Overthot]

Ok, it's been about a year since I was on here. Life is a mess, but I finally have devoted some time to practice again.
I did a couple portrait studies from references online, not much in terms of conceptual stuff. I realized though I have tons of bad habits to break and I'm basically starting over. Back to value, form, and composition. I've been spending about 4 hours a day working on stuff, here's what I've done since I started back up about 3 weeks ago.
Also, I'm working on GIMP and still learning the interface.
