Ahh, the nostalgia, it reminds me so much of one of my mum's friends apartment, in Bucharest, brings back so many good memories :D.
Anyways, I love how you put the background from your drawing with the jungle waterfall and girls in that frame there. The texture on the chair doesn't really give the impression of a material, more of a vinyl or a drawing on it. And the floor make's everything seem out of place, but all in all, it's very well done.
And btw, her head turns too much, you need to see a little bit of the other side of her face, like, just the outline of the cheek or something.
Very well done :D
Btw, criticism is improvement, improvement is awesome, awesome is Sab, so yeah, keep doin' ya thang xD
