I’m only just beginning to look more in-depth than I previously have at mixing techniques myself. Her voice has quite a large dynamic range so I think the right kind of compression at the right ratio and such would help a lot as it does become a bit too harsh at peaks. As to what they would be, I don’t really understand compression properly myself atm. ;D Her voice isn’t quite my thing but it does draw one in with its uniqueness and I think the main problem is the peaks of the dynamic range being too harsh. The words are a bit hard to discern though. According to Dave Pensado on his Youtube videos boosting the vocal at around 2khz can help the consonants to cut through better. He also mentions cutting at around 600-700hz…though I can’t actually remember his reasons for that so I’d need to watch it again. ;D And of course wouldn’t work for everything.
The tracks could really do with percussion though. Storm King says it’s pop-rock but I think a nice jazzy brushed kit would complement her voice and the style really nicely, especially with that rhythm. ;D The melodic and rhythmic combination for that track is nice and could probably get stuck in ones head better with some nice drums accompanying and some vocal mixing like controlling the peaks a bit without completely ruining the dynamic range and making the consonants clearer.
Some cool stuff there though, I think it’d be worth spending the time adding some drums and stuff. Perhaps some others from the forum would want to work on it if you don’t know anyone that can/has time, who knows.
