The perspective of snowmen is a little off and maybe shifting the color balance to a little more red on the snowmen would help. I think this one looks a little more challenging to do than the other. The other is dark which is usually what I do to make it harder to find mistakes. I think on dark images, you still need to add a light source from an angle to add depth. I do like the creativity of it. This is a difficult match to decide. Best of luck to both.
The other is a good idea, but is too dark and has perspective issues with the mirrored guns. This has some lighting and depth shortcomings, but is the stronger effort. The cutting out is well done.
