Warning: I'm a bad critiquer but let's give this a try...
All I have to say is I'm extremely jealous of your EQ.
2nd Pic: You're maybe
leaning on the neck a tad? (Or maybe it just looks like that because of your sleeves? Idk.) And looks to me like you have a little too much of a release, also.
4th Pic: Heels!
I can't really find anything wrong with the others. SUPER job!!!
