I'm not very experienced with Reggae, so feel free to disregard this, but:
There's something off about the bass, but I can't quite put my finger on it. It's almost like there's a stereo enhancer or something on it, or it's been double tracked (very tightly).
And I would've had the guitar on the left maybe not quite so far left, maybe with a bit more presence to show the percussive aspect of it a bit more.
I think it could do with a little less reverb overall (mainly the guitar). Not much, just enough to bring everything a bit further forward. (But I'm listening on headphones that bring the reverb out a bit, so that could just be me)
Although, this sems a bit more "I would've mixed it different." It's a good mix, and you could use it as is if you want. I just think it could do with just a little more work if you want a broadcast quality album.
