Hey man, good montage and good clips. Remeber less is more, slow down cetain clips to make it more dramatic. Also try get killstreaks instead of clips(More snipes in one clip). Maybe some better fonts and graphics but your definatly getting there.
Your pretty good with sniping. [tip] If your going to zoom into the screen i suggest you zoom in when your going to get the kill. Lol. When I try sniping I fail. =D
