For someone who's never designed a website before, you've really done a bang-up job. It's tight, communicates your information very effectively and presents a unified appearance. The loading's a bit slow for me, but there's nothing that can be done about that, since I'm in the U.S.. Still, some of the kids around here could learn a thing or two from your site.
Your designs are very professional, and I really hope that some of these companies take your suggestions into account.
I like the logo redesign you did for American--the incorporation of the old TWA double-globe was very creative. It'd be nice, though, if you could enlarge the logo on the main body and the corresponding "American Airlines"--I doubt that anyone would be able to read it if they saw that aircraft at an airport today. Also, moving the stripes down is an interesting change, but I think a new American scheme would have to incorporate more of a change in these stripes...perhaps a "wavy" form down the body?
The yellow in the SwissWings scheme is a very daring choice, considering that the trend in paint scheme designs lately seems to be away from bright colors and towards more drab choices (like the grey and red SwissWings model) or the plain, European white schemes. Personally, I like your scheme better than the red and grey one (reminds me too much of Northwest), but I think that a better choice as far as color would be to make the yellow more an orange-yellow (perhaps butternut yellow?). That way, in my opinion, the yellow would blend with the red better in order to make a more unified scheme. Alternatively, you could make the tail this orange-yellow color and keep the body in the present yellow, giving a gradation from red to yellow as you go forward on the body of the aircraft.
Honestly, I didn't particularly care for your Iberia scheme...it seems to me, anyway, that if they went with that one, it'd be a step down from their current livery. It just seems to me that the grey makes the scheme look way too drab...the nice thing about Iberia's current scheme is that it's bright and eye-catching, although I do think that they need a new one. I did, however, like the way you eliminated the "IB" logo on the tail in favor of the crown, and how you spaced out the "I B E R I A" name towards the middle of the body. Those are good changes that Iberia should incorporate into their new scheme, in my opinion.
Would you consider doing a scheme for the renamed Canada 3000? I believe you posted something about that near the end of the C3 rebranding thread...again, if you didn't see it, here's my take on what the scheme might look like:
I don't have the benefit of professional design programs, images, and the like, so I just drew it up in about 15 minutes. My comments on the other thread go into greater detail on it, but basically, colors can be changed around to suit the image that the airline is trying to project. I chose "Royal Canadian Airways", because a lot of people (including myself) thought it sounded very good, but C3 could be anything, including remaining as Canada 3000. I'd be very interested in seeing your take on a new scheme for this carrier.
