It sounds nice~ I like the voices a lot especially the girl but they both seem to be a little too loud. Either that or your background music is too quiet. I'd suggest either turning your voices down a bit or turning your music up a bit. I know it's hard to get it to the point where your voices don't get overpowered or sound overpowering but it sounds nicer once you do get it.
I'd also play around with some effects more. Especially for 1:50-2:05 where the voice has a lot of distortion and effect on it. I'm not really good with effect names sorry...OTL
But it's a pretty good start~ The mixing could just be a bit better.
