Will I become a good composer?

[gesh14]

I'm almost 15 and I've played the piano for more than eight years. I've always loved composing music. A lot of people say that I have a talent and my music is very good but I want to know what other people think about it. Here is a video of me composing: http://www.youtube.com/watch?v=28UHdujNyaM
And compositions that I like:
