Right, negatives first. Let's start off with the mix.
The first thing I notice off the bat is that there's very little discernible bass in the mix. The kick is weak, and the bassline is hard to hear during the main portion of the mix. Add that to the fact that there's very little in the way of bass frequencies throughout the mix, and there's a bit of a problem there. I suspect some compression will be your friend on that kick. What's your current DAW? I can give FL-specific tips much more easily, heh.
The piano could really use some more quantizing, honestly. I know there's a line to balance between natural and mechanical, but you'll almost want to stray more towards the side of mechanical for a song of this genre, IMO.
Do you have reverb on that open hat? I'd take a lot of that off, if that's the case. Honestly, the 909 open hat doesn't really make a good driving, rock-esque hat, so you might consider just putting it in for every off-beat.
I'd take a bit of reverb off of the snare, too. You'd be surprised how little reverb is actually needed on DnB drums. Definitely lower the high-cut, as well, since those extra high frequency reverberations aren't really helping for the snare, either.
Some of the drum fills are just a bit awkward, with the hat changing its rhythm just enough to sound a bit contrived.
Also, just as a suggestion, I like to stick a sampled break (like an Amen break or something) or two into every DnB song I make. Just helps to fill out the spectrum a bit. Not every song needs to have this, but I like to use breaks a lot when possible.
Now, let's get to the good stuff. I really like this arrangement, and the guitar work sounds really solid to me. Your synth leads are quite nice, and I love when you intertwine the leads together, whether they be guitar or synthesizer.
Overall, I'd say that the lead actors in this production have really got their acts together. Now, all you need to do is focus on the supporting cast. Get a bassline in there so that we can hear it, get the drums tightened up (maybe consider different samples?), and really make this thing shine. I can think of no better example to give you than my own recently-released track from the DKC3 album, since it's almost the exact same style. Hard-driving, guitar-laden, synth-lead-toting DnB. You'd be appalled at the amount of compression I used on the kick and snare, haha, but that's sometimes what it takes. You can really change the sonic character of a drum sample by throwing it through three or four different compressors.
Hopefully this helps out!
