Why did your female voices come off the best here? xD Your deep voice(s) weren't all that deep, but nice accents. From this it sounds (no pun intended) like your range is mid to high but definately not bassy low.
Side note cause I know this will be mentioned at some point: I got LittleKuriboh and Egoraptor from two of your takes. Just listen to them and you'll know which I mean.
