Hello and welcome!
First things first: I hope you like Mahler!
Oh, I love the viola so much! One of my favourite instruments perhaps, such a beautiful tone!
I am also a composer, and at the age of 14, it is my ambition to be a composer and conductor for my life! There's a good section of the forum dedicated to it's composers called 'Composing and Performing'. Hopefully you'll make your own page there sometime. Mine is called 'Hogan's Home'.
I hope we can hear some of your music soon! I also used to compose in the romantic style, and still can't stop myself from doing so sometimes. And the composers you mention are some of my favourites, so we should get along well!
Thanks for the introduction, Elliot!
