Wow! All the details look great. I love the lapels. Really beautiful work. I think for the next one just play with the front balance a little. It looks like you might need a little extra length on the front and perhaps a little extra width across the back, but tiny amounts. It's a win for sure.
I can tell you what I think I see. Unfortunately, I'm not great at proposing solutions. Overall, it's a good effort and that's not the easiest cloth to work with.
Back
Much of it looks too small. The collar is right up against the back of your neck, creating a slight bulge. The upper back fits, but it looks a little too tight. Starting in the high-mid back, I think you need more fabric so the coat can drape better. The reason the vents aren't closing may also be because more fabric is needed.
Sleeves
The sleeve pitch may be off; it's particularly pronounced on the left side, which has a deep furrow in the back. The sleeves are too small for your arms. Look at the strain on the undersides in your first photo. I think it's because the sleeve is too tight, but there's no smooth transition between the shoulder pad and the sleeve. Did you use a sleeve head? Maybe the shoulder pad is also too high?
Front
I think you may also need more room in the front to close the coat.
It could be due to the way you pinned it closed or your stance, but one coat front is longer than the other. That also could be the result of a higher shoulder (which is common). You may be able to correct that with shoulder pads of different heights, or you might need to cut a different armscye on one side.
