Sound pretty cool dude Only thing I'd say is when you're about to change from the verse to the bridge or chorus try using a different "fill" at the end of the verse or use a different note so it gives you the chance to do a key change and take the song somewhere else.

Keep up the good work.
thanks mate, actually in the first song it's a breakdown riff before the end of the song ^^ and after that it's some samples of another song
