Let me start off by saying that this critique is written on the basis of this being the artist's first attempt at silluetes.
The vision score is high. I have seena lot of silluetes in my time, but in terms of vision, this is one of the more successful attempts at that. This deviation has a fresh approach, and the artist successfully aviods many of the clichées. But naturally, not all of these can be avioded.
For the same reasons as mentioned about vision, the originality score ranks well.
As far as technique goes, this is a well executed photo. Yet, there are some minor things around the frame and the fingers' contact with the glass, which could have been more smooth. Small things, yes - but still worth mentioning. In having a minimalist expression, this photo avoids having a clutter of details, which is only a good thing - especially considering the artist's limited experience with sillouetes.
Finally, to sum all of this up, there's the impact score. The title, which is a very important factor, seems to have a clear connection with the photograph - it is a logical and yet very elegant choice. The effortless interaction between the light and the dark sections of the photo is an excellent feature. There are, off course, certain minor flaws, but for a start this is quite a good photograph.
