I say it's pretty good, but could use a little work with her nose (I'm pretty terrible with noses myself, its usually why I rarely draw character that have them).
I can relate to that too, most of what I draw has no real subject matter. If I think of it I draw it. I even drew myself in someone else's art style but drew my skin a little to dark but I don't really care because it was my first time doing a self-portrait anyways!
Funny thing is I actually have family that lives in Texas. I'm pretty sure they see this it's from the golden age of Spongebob Squarepants, ever now and then it has moments like this but rarely do they make me laugh as hard as this.
