Some portrait practice I did last night during loafing time. . . I wanted to wake up and improve on it this morning, but I can't get in the groove again, nothing looks good, so I gave up XD

I would really like to make an alternate cover for 'the year of the flood' by Margaret Atwood. . .So I tried to make her look a little longer, thinner, and tireder than the model I based it off of (http://distome.deviantart.com/#/d48patj), because I wanted her to fit my image of the character Toby better.

I don't really have any experience with portraiture, or really anything (I sketched a LOT when I was younger, but in the past five years, I haven't been doing any sort of 'practice' work, if that makes sense) - so any critique is very appreciated.
