I'm not a coach (except I coach myself).
You look very flat footed, but I could be wrong.
Not a coach. but you are pretty fast for a white guy.
It looks as though your foot strike is slightly forward of your knee, with your foot excessively supinated. Work on foot stike vertically below the knee, more centrally on ball of foot to minimize above observation. Larger ranges of motion should be established in the hips, not only with respect to knee lift, but full extension of the hip with each step. The extension of the hip should drive the foot into the track surface. I see you leading with the head. The head should be kept in a constant, neutral position with respect to the spine. Work on relaxed movement of the arms, shoulders stay down and relaxed (yours appear tight, flexed, hunched), the back arm swing should stay under the elbow (you are swinging excessively to the rear, creating some torso twisting). My two cents.
There's something shut off on your right side. You clearly have more force striking the ground with your left leg.
It's hard to see from that angle, but it looks like you have some tibial torsion on the right side, causing your right foot to come severely under your center of mass. I would guess that your right glute is not functioning fully because of this. Your ankle may be shifting inwards on foot strike in order to keep you balanced and moving forward.
Related to that, it seems like you have poor lower ab strength (along with proportionally too much abdominus rectus strength contributing to that slight forward lean in the torso) resulting in less than optimal knee lift. Again, if this is the case, you will have less than optimal glute function.
Film yourself head on. Have the cameraman step out of your way at the last second while you continue on straight. Look closely at the right ankle, tibia and the foot strike in relation to the mid line of the body.
You look like you could use some flexibility improvements.

Good advice. The foot plant looks off. A bit flat footed due to foot strike being ahead of the knee. You look like you are sitting back into your hips instead of driving forward. Knee lift could be higher. Couldn't see the beginning of the race but I bet your drive phase is abbreviated due to the above reasons.
You're losing a lot of energy it looks like when you bring your foot in front of your center of gravity and then bringing it back before it even touches the ground. Solution: Work on the BACK of your body, as that is what drives you forward. Don't reach. Also, your arm action is pretty severe for a stride that isn't even that long.
Your stride also seems very short, about as short as mine, and I'm a distance runner. You are driving your knee correctly as if you were going to execute a long stride, but it's just not happening. You need to work on really pushing off with you back leg. The angle of your back leg at push off is similar to mine, as a distance runner.
