Please check it out if you have a minute (or ten )
I'm really looking for feedback to improve and get any idea of what other people believe of my mixes so please comment or reply if you have any criticism or tips or even even you believe I just deserve a nice "Well done "

*It's done on Traktor Scratch Pro with a Xone 4D so if anyone has questions on the gear or even just wants to see it in action (I remember I was scoured the internet to find videos of the 4D before I bought it)

Anyway thanks in advance
Keep safe,
Kieran
