It's more drum and synth than drum and bass but that's fine. Level of the drums is OK by me, I think they need the bass to cut under the synths. Plus with synths like that you're never going to get impressive bass anyway, they just take up too much room.
I think the synth part needs work. It's a bit of a wall of noise but I can hear that there are single note melodies in there which need to come out more. Also they're a bit too fast and messy, I'd use fewer notes in the melodies. Maybe that's the character of the original though The bit at 3.14 where you strip it all back is good.
