I rather like how it's vinyl length, but keep in mind most of your audience here has ADD in varying degrees of severity, so it's unlikely many will sit through anything over 3 minutes long unless they really like it, nevermind 10 minutes plus.
That aside i listened to your first upload aswell and i think two things would really help you, firstly record/compose your pieces in a slightly higher volume cus your current level is hard to hear :3
Secondly do yourself a tremendous favour and try to copy something you like, not so much literally but try to get close to the sound of whatever you like listening to, you'll learn to improve faster then just jamming away on your own.
All that said, i think you're off to a great start, keep at it and have fun
thx :) hardstyle baby xD!
