0:43 5 shot burst is a little too much for the AKM. You can't rely on spraying like with an M4 or AUG. The spray that happens next is uncontrollable, and your hand wobbling doesn't help. Try to work on improving your control. I suggest using Virtual Stock.

0:50-0:52 The way you rounded that corner is too risky. At 0:51 your gun should be trained at the corner of the entrance to B as you turn, scanning each part of the area outside
B as it comes into view gradually for anyone coming from behind. At 0:52 you finally raise your gun at the box. 

1:01 This illustrates what could have happened at 0:50 if someone was there. Your gun should be aimed at the opening between the doors, but since you had the bomb, you probably should have been planting it anyway.
