Uhm, you don't seem to at all use anything to aid you in your proportions/anatomy. I highly suggest using methods like this one if you're going to draw a certain person, it saves a lot of time and makes it a lot less frustrating in the end:

That guy has really great tutorials on a lot of drawing principles, so if you want to seriously improve I highly suggest checking his videos out.
Overall though, I'm impressed with a lot of this. The cat one especially caught my attention. I loved the mood it set and it's sort of abstract-ish yet very clear. The other ones were also really good. I do somewhat have a feeling you took the picture of your self portrait from an angle for a reason. Did you fuck up the proportions or something?
The new one is good, but you could save yourself so much time just using these quick little tools. I'm sure she'll appreciate it though!
Edit: also, you could use some work on shading eyes now that I look at that some more. It looks really silky the way you drew it. Also don't be afraid to add some small black lines in light hair so it still looks like hair. It looks kind of like you didn't draw the hair yet.
