its alright man, uv got more musical ability than alot of people writing at ur age i think.
i think the main thing you might wana start lookin at is your sound levels, you need to get all the levels sorted out so they sit in the mix right,
at the moment your lead is too loud and ur drums arent really loud enough and the bass needs sorting out etc, once you get a few tracks going just start looking at the arrangement and how loud certain things need to be.
lucid is spot on, levels are a bit of a mess. he's also right about your musical ability, i think this is a really good start for someone so young. you seem to have a good grasp of dnb concepts early on...
