Saida "vector" portrait

There are a lot of very impressive artists out there and lately I've been seeing tons of talented ones making magnificent vector portraits. After countless failed attempts at making a fairly accurate portrait of this lovely girl I used to see a lot on a local noontime show (and whom I have a really big crush on),  I decided against my better judgement to try my hand at doing it vector style. I'm obviously not as adept as most vector artists, and have limited painting skills - learning mainly on self-study, but I hope I did pretty well on my first try. This was done on Photoshop which isn't really what real vector artists use, but it's the only digital software I use for most of my artwork.
