I'm going to try and make a few suggestions, and I'm hoping they're "constructive" enough.
1. The blue: yes, blue and red lettering has won awards (and North Carolina's license plate is pretty great), but there's too much going on. From the waves at the bottom of the fuselage, to the stripes on the tail, to the jagged pattern on the engines, and the odd light blue on the top deck of the 747, it looks cluttered. If you have just one or two of them, it's fine. But having so many things going on at one time makes the eyes strain.
2. The font: Red provides a nice contrast. But, if you're going for a large airline (especially one that operates 747s and is #1 on S1), then you're going to need a different font. Writing "Wright Brothers" (especially with the apostrophe) with that font looks cartoonish and unprofessional. I'd recommend https://www.dafont.com/ and http://www.1001fonts.com/ for a new font: it's free, and you can make sure your text looks good before you download it.
3. All the characters: If I'm counting correctly, I see two airplanes, one man, a Boeing logo, your profile picture, and a bunch of text ("First in Flight," "Five Sins," "747-8i") smattered haphazardly onto the fuselage. If you're going to have the Wright Flyer as your logo, then so be it. But using actual images and then pasting them on isn't going to do it — that's unprofessional and messy. Same goes for everything else you've added — there's certainly a place and size for all of them, but they can't just be cropped images that have been pasted onto the plane. You need some organization in order to improve clarity and visibility. Otherwise, it looks amateur.
You're off and running in the world of template making. But before you keep going, you need to slow down, take some time off from the templates, and then come back to them with fresh eyes to see what needs work (and no, bashing Med's templates does not count as taking time off). Just like Rome wasn't built in a day, neither was the perfect livery. I see some promise in this, it just needs some... improvements.
