Well, natsugi, it's good to know more people who tend more to classical and I'd gladly recommend some composers for you; the problem is that there are a lot of different styles and not all might be of your liking.
Judging from your examples, Romanticism is your forte and ironically, my weak spot. Don't get me wrong, I like some Romantic composers but I tend more to the "intense" music (although not always).
Maybe you can check for Schubert's works, specially his Improptus' and one of his most popular and powerful, the "Erlking".

Or maybe you'd like something more calm, that would be Schumann, here's his famous Traumerei:

Or something more contemporary yet romantic?
Here's a Romanza and a Valse Sergei Sviridoff, played by a friend and yours truly (I'm the one with the ponytail)

Well, I hope I could be of assistance, and please, continue your liking for Classical music and try to promote its listening among family and friends, for the better future.
Cheers.
