A mate of mine asked me to do a remix of something he did - it features his slightly camp voice and some quite offensive lyrics, but I learned a lot about Renoise putting this together.
Keep finishing things even if you don’t like them; it’ll force you into a good work ethic and help alleviate the "got-GBs-of-loops-but-nothing-complete syndrome that pervades many a musician (including myself 
)
Anyway, IMHO, the intro is too long and I really don’t like that high-pitched sound (~1m); sounds like nails down a chalkboard. This maybe the reaction you’re looking for artistically but it’s not for me…
Once the track gets going it’s not bad; but I would look at how the vocals sit. For me, w-a-y to much delay as the vocals are not distinct enough. Have a look at this link this link and pay attention to 2:15 onwards. I think that might help 
I would also look at introducing some movement to the pad sound like some chorus/lfo’d filter/reverb/flange or summit
Also, A/B your mix in mono; you’ll be surprised how much will get lost (ie delayed hard panned vocals). I dunno how to do this in Renoise yet but I use this plugin to toggle the Master from stereo to mono
HTH
Good luck!
Haha, thanks man.
The ‘stems’ supplied to me were recorded on an iPhone mic 
including the vocals, which already had reverb on them, annoyingly.
I wanted the intro to lure you into a sense of it not being a jungle track, and just to be an awkward sound, something quite horrible and miserable - which also explains the horrible sound you didn’t like! That was a vocal; pitch bent then recorded through the inbuilt mic, sort of sounded horrible to me like a worm burrowing into skin 
Definitely agree on adding movement to the pad sound and just about to watch that video - thanks very much for such constructive feedback! My next track is going to be using sounds I found myself I think. And thanks so much for the plugin link up!
