Reply to My remixes

Hi guys
My name is Patrick and I am a 15 year old producer from New Zealand. I have been playing around with ableton for about 6 month and just started remixing last week. I would appreciate it if you could please check out my tracks and give me some feedback and advice as to how I can improve.
Thanks
Patrick
