Well that's a pretty nice website for anybody, let alone one built by a 16 year-old. Nice job, Harry. It looks nice and clean and professional. As far as suggestions go....I would consider tweaking your logo so that it's more than just text. I'd also consider breaking up the homepage that is above the fold, just to break up all of the red. Maybe place the text in boxes or change some of the text color, something like that. And make sure that you give people a clear reason why your app is better. There are a lot of travel and discovery apps out there, and competition is fierce. So clearly spell out why yours is better and why everybody needs it.
But all and all, nice job. I wish you the best with your new site and app.
