Well...
I liked the concept, though it was very short. Sorry to say... but your animation is lacking, try looking up tutorials on human form and proportion, as well as clothing. You may also want to brush up on your sniping tactics, you've got to be an idiot to light a fire if you're trying to stay concealed (your camoflauge needs work too) try illustrating ghillie suits and so forth, and your gun design is appauling, you need to seriously examine fire arms and ballistics, and your scope scene was terreble. it was 4 lines, a black template with a circle with alpha around 20 should be suitable... also, when sniping, the best position for sniping is prone, however others will work... your kneeling position... was not. try buying the marine corps or US army sniping handbook... it will teach you alot, and back to the scope... the propper position for the eye would be 3-3 1/4 inches away from the lense... not directly on it. sorry mate, had to point those things out.
