Hey SataQ, Ive always loved drum and bass since i was a kid been listening to it for about 13 - 14 years now.
Starting off with Andy C, London Elektricity, Ray Keith, Shy FX, DJ Hype, U.K. Apachi, Goldie, DJ Fresh, Cyantific and Sub Focus.
I will give you my personal thoughts on your songs, Me im all Liquid Drum and Bass second choice is Dark drum and bass lol, The song you posted was liquid dont get me wrong but me personally i would say use a better snare for the one you have. Its a great remix you made but trust me could do with more lets say more motion and sound. Plus your build ups are abit confusing weird sounds then into liquid drums, personally i would use a light ambient/ambience build up sound with maybe a piano and maybe a lazer sound. Trust me they work great! Since i used to do my own DNB tracks and remixes. Now i work free promoter for Hospital Records in UK. They are the best in Liquid and drum and bass in the UK by far.
Your dark drum and bass build up was great but the bass was too Jump up DNB for me and the drums was too quiet for Dark drum and bass listen to someone like Spor or Noisia. More you listen to peoples sounds the more you make more idea's for songs and dont be scared to use dubstep bass and mix it up in your dnb tracks plus there snares for your dnb snares for dark dnb. Plus dont be scared to combine loops of drums together thats if they dont sound too over powering in the song mostly use them for build ups or break downs.

Hope this helps! Keep at it bro!
