"I was sure I missed the first one because of the angle I tried to shoot(straight down)"

Lesson one: Don't ever assume anything. You should have gotten down and confirmed the miss before ever even thinking of a second shot.

Lesson two: Don't take low percentage shots i.e. shots through brush, straight down shots, shots at bad angles, facing shots etc.

Lesson three: Get your ass to the range and learn to shoot and stop trying to justify your mistakes. Learn from them and don't repeat them.
