Ekko Montage - please give me some hints on how to make my montage better :D

Hi guys this is one of my first montages and i really enjoy making them but i am not that big of a youtube i have like 120 subs or something but it would be a really big help if you could give me some hints on how to make my videos better.

And if you actually like what i am making you can always subscribe. that would be a huge help :D

Hope you enjoy <3

Btw i am giving away 5 mystery gifts when i reach 150 subs and i just choose a random "ACTIVE" sub

Continue a good day :D
