Marco, big welcome to the forum. Two things first; you need to post this in the your playing section of the forum. Just a heads up for next time. Second, I'm not a DnB fan, but I love some of your concepts.
Checkpoint; Some really cool ideas here. Great drum sound. Lovely groove in the simple parts, but the timing fell down with either bass or drums complicated fills. Shame, because it detracts from a really interesting old school slap funk bass & popping drums vibe.
Magical romance: Loved it, really. Superb composition & soulful feel. Almost sad, lovely. Not a lot going on for the drum fan, but who cares!
The other tracks all had moments of interest but also some basic timing drift issues. Overall, very interesting, and at least for me, different.
