Oldies but Goodies III - Sleepin By The Window

I go to work by train every day , and every day I see the same people with their "here I go to work again" face, but every day, at he same place, in the same position I see this two girls...sleeping by the train window,
and this is really funnie, the way I allways see them there...what can I say...its an inspiring picture and it got me inspired to do this.
Not the professional final touch here but I did this for fun so I just tried some lines and colors not too much time on this.
