The things that work in no. 1 are
1) the long, streaked background has no detail to distract and implies loads of speed and feeling with the motion blur.
2) the horizontal format as opposed to the more square in number two also implies greater motion streaking from right to left in front of us by providing us with a panoramic view..
3) Number two has that extremely dark spot in the upper left hand corner which is way too commanding of a distraction robbing power big time from the overall comp. This is fairly much gone in no. 1.
4) The second shot has the bird almost centered which locks him into a state of greater stability. The second by placing the subject to one side--destablizes and creates dynamic balance---movement in other words. This could be accomplished if he was on the on the other side also. But the zoooming by feel is only accomplished with him on the left.
The point, purpose and intent of your no.1 shot is clear.
