Hi Daniel and Welcome to NPN! 
This is a terrific image with lots of fun action, I love the low perspective and the low angled early morning sunlight creating the distinct shadow on the underside of the left wing.
The running takeoff was perfectly captured and the takeoff being directly into the morning sun is great!! (The title is well suited. )
Excellent image overall!
In my very humble opinion:
I agree this needs more canvas on the left and a brighter and more defined beak.
I also think there are a few more things that need some attention like:
- The area between the neck and the right wing needs to match the rest of the BG in terms of exposure.
- There is a fair amount of digital noise that can be mitigated to a reasonable degree IMO.
- The focus on the eye and head are a little soft (as a result of the noise?) (or maybe just artifacts?), not sure.
Note: Any edits are always best done to the original RAW image file rather than a compressed jpeg file like this.
I hope you are shooting in RAW.
I took your image into Ps (Photoshop), copied the original layer, then run that copy through Topaz Denoise AI, I used the Standard mode in Denoise with the strength at about 7 or 8 (just enough to reduce the noise but not so much that it created more artifacts).
Then I created a new layer of the beak using the Polygonal Lasso Tool (I copied and pasted the selection so the beak was on its own layer), then adjusted it with brightness and contrast.
Next, I used the crop tool to add canvas to the left and checked the “Content Aware” box at the top so Ps would fill it in for me. Note: I noticed a few repeating patterns so I used the clone tool at about 50% opacity to remove any repeating patterns and to add clarity to the water highlights.
Then, just for a little clutter removal, I circled some of the stuff in the water with the Lasso tool and then went to Edit>Fill and used content Aware to remove those.
And finally, since the eye was a little soft, I used a very small brush of 2 or 3 pixels in diameter while using the Smudge tool and simply pushed a few pixels around to make it look like the eye was nice a sharp (well…reasonably sharp).
I just read in your responses that you have limited experience in Ps and Lr so that helps us to know that.
Instructions for each of the tasks above can be found on YouTube but I/we would be happy to help further if you get stuck or need clarification on anything.
Below is a screenshot showing the layers I used in Ps, I hope that helps!
The example edit below is just to demonstrate what can be done in Ps (and other programs).
I’m sure I missed something in the explanation, I usually do. 
Some of this will seem intimidating but the best way to reduce or eliminate that is to watch pertinent videos closely and spend as much time with Ps as you can.
Lr is great for color adjustments and masking (as well as a few other things), but Ps is the real workhorse IMHO>
Again, great capture!
