Your voice definitely has a marketable sound to it. I could easily imagine hearing you alongside popular artists on the radio, unlike some singers who, while talented, lack that element. You can hit (at least) A4 in your mix, which is fantastic.
I'd say that your original songs are alright. I get it if your focus isn't super-commerciality, but I didn't find them as engaging or memorable as could be.
I used to write pop music and have some of my own experience with reality TV, but my vocal folds are shot. I don't know if you were looking for in-depth comments at all, but it's always lovely to see the work of other musicians. Your best performance here is "Lights" in my opinion, not to mention that the notion of a former Idol contestant using Showdown is pretty rad. It shows how Pokemon transcends different lifestyles, or something.
Anyway, your stuff is truly great. If a full-time career in music is still somewhere on your radar, I hope you haven't given up.
