Wow it looks cool actually, unless you intended it to be super realistic (blending the stock photos like it was part of one scene etc. yeah you need to practice lots) this piece actually gives of a unique feel. Surrealistic feel? I can't describe it. It has a story within it. The expression of the girl is interesting, it shows that something is wrong or something/someone is chasing her, or maybe she's looking at us, or maybe she is the perpetrator of the crime aisndinasdin :D This artwork feels so cool.
I guess practice some more (but your style is pretty unique. But then if these are actual drawings made by yourself, then omg, you're a master :)
