The first shot of any video (and establishing shot) functions as an "introduction". It has to capture interest so the viewer has a reason to continue. The very "long shot" (as in long, medium, close-up) you use doesn't really do that, and the next shot doesn't either. Both are too "long" in distance and don't establish anything interesting. Sometimes its better to establish on a subject in context rather than a massive context only shot.
The traditional progression is "LS to establish, MS to draw interest focus, See you to bring you to the specific subject"...then it goes from there.
The current audience doesn't accept slow pacing very well, us older folks do. That's why the opening 15 seconds have to grab the viewer quickly, and compel them to stick around. Don't move too slowly, either in camera moves or pacing.
Nice shots though.
