Well I'm not really much of a house fan, but for a first song, I think you did a pretty decent job.
The title is a little misleading to me though. With something called 'Forgotten', I assumed it would be a mellow, sad song. This sounds like a more uplifting tune to me, like a youth with a strong spirit persevering through a struggle.
Maybe I'm missing at what you're going for. It could be about discovering a forgotten land or something, but whatever the reason, the song was still nice.
