RnB Ballad is sounding very nice, vocals ontop of that will sound propper!
My internets a bit gefucked so I only listened to 4 of them, and I'd say that was my favourite. But really man play with the attack and release on that violin, just to get it to flow a little more.
Other than that I'm loving the quality, if you're using ableton then stick some cymbals into a sampler and reverse them, play around with them, just to fill the track out...
