Nice pad! Im not sure about the vocal, either it doesnt fit the style of the track or its simply too overbearing?
If it were me i would loose the vocal and work on the pad progression. Make a really interesting melody instead of relying on the vocal to keep the track interesting...
The drums are ok but maybe half tempo feel would suit better?
Just feels like two different tracks as it is for me, i understand you would like to use the vocal but it doesnt sit well over dnb drums and analog(ish) pad... Maybe try a more techy style for the vocal?
