Really, really nicely done. The most minor quibble is the lighting over her back thigh. Not sure what is going on with that streak of light across her leg. It doesn't look like it belongs.
I'm going to be super nitpicky though because I feel you did such an outstanding job, i'm questioning why the model is wearing contemporary panties? Was it too hard to fabricate something identical to the movie character using bandages?
Agreed this is an outstanding composite.
Watch the lights though the shadows come close to calling out the background in a lie.
I agree with the panties comment to a point - I wish it didn't have the frilly edge.
I think her pose is very good but a little static - a little extension on the forward leg would have added some "action". As it is it seems a little at odds with the gun and the relatively contemplative pose.
Great job overall!
PS: I'm really digging the shading and color cast of the background - really really great choices.
Sorry, please dont hit me with a rock or something else... but i do not like it... For me it dosnt look real, Photoshop is to obvious in this picture. The 2 Pictures dosnt fit together. The light is diffrent and it looks artificial.
Dont get me wrong, its not a bad picture but its obvious a composing.
Edit: There is a small line near the model across the Picture.
The only thing I do not like is the weapon in her hand. The "original" was the weapon, did not need one! Whe the hell is this model? She is F-A-N-T-A-S-T-I-C!
