is this lady gaga? lol... good job for this!

Mmmm spooky I like it GL

Nice work.

At first sight i tought you made the machine from the given source, but when i checked sources i noticed u did not. So thats a complement on finding the right source.

First i'd like to say that personally i'd like to see the given image to be chopped to be used a little more, but that is personally.

I got a few things that might ( in my eyes ) need changes.

I think the girl in white, still is too much white.
The light source on the girl comes from the left and right hand side,
while on the machine, looks like comes more from top and front side.

For the person in the back ( i do not think it adds much to the image, but that is personal again) might need a color layer on the top of the person.
Also for the shadow u might want to duplicate the layer and give both layers a mask, then blur or stretch the 2nd layer.

These are just my ideas of improvements, and you can ofcourse disagree.
See this as help only and not as, someone trying to see only the bad things.

The idea is to help you get the most out of it.

Good luck in the competition.

It may be my monitor, but I find it a bit too dark.

But from what I see you did a good job with your sources. Maybe a stain or two on the woman's white clothes may help to integrate her more in the image.

Very nice work author...great source find too...u made super cool composition here...best of luck

Thanks for the suggestions, but due to the holiday break I never had time to get back to this.
