Photography is often described (fondly) as "painting with light," but it's really not at all similar. Many situations, particularly involving living animals, take a lot of patience. This photo is a classic example of snapping at the right moment (when any other would not have had anywhere near the same, powerful effect).

Vision: The passive look on the tiger's face contradicts the presumably carnal nature of his instinct. He looks like a giant house cat munching on a treat--but the shape of his body and the position of his head exemplify power and majesty. His eyes appear to be looking into the camera, and thus directly at the person viewing the photo: you can almost see what he must be thinking. The image itself is powerful in that regard, but certain factors detract from that power. The tire in the background and the gray block that appears to be a cement slab at the left edge and behind are the main culprits. The tire could be cropped--the slab, probably not, but it's less visible anyway. The photo's color is also a bit dull; maybe consider touching it up, brightening it, and increasing contrast.

Originality: Tigers are renowned creatures, and as such are popular targets of cameras. He's a zoo tiger chowing down a treat: but more importantly (and unlike most of your other work), you can *tell* he's a zoo tiger. Originality is hurt by that, badly: the photo looks very similar to thousands of house cat portraits across the internet. Still, not many people have regular access to zoos with tigers: it might not be the most impressive way to pick up originality points, but it still results in an image people can appreciate for being something they don't see every day.

Technique: The color I've already mentioned. The tire and cement block really weren't avoidable. I wouldn't count them as part of your technique. But there is a problem with the photo that you're already aware you made: camera shake, it looks like. That's just something you learn to correct with experience. Sadly, there's nothing you can do to fix it in post-processing.

Impact: Despite the issues I've mentioned, the tiger is a beautiful, intense, and rare creature, and the photo succeeds at impact mostly by virtue of that fact. Further, the expression on his face is priceless, and he's difficult to ignore with his jaws open slightly the way they are, ready to bite down on his treat. Without thinking too much into it, this is a powerful image--minus half a star only because the camera shake sort of dulls the intensity, if you see how I mean.

Overall, the tiger himself looks great (bar the camera shake). The image's major drawbacks in my opinion are the weak background and the dull colors. Still a powerful image. Nice catch.
