Thank you for sharing your clips with us. You have a good musical ear, nice style and very nice tone. That being said, I think you could use some work on connecting more in your body when you sing in your low parts and don't let go as you go higher. Right now you have a REAAALY beautiful low part of your voice, and a disconected high top.
Your voice seems it's a voice which likes roundness more, and you're spreading all vowels, with a high larynx, this causes the sound produced to sound yelled and completely different from your low voice. I should stress that this is a disconected from your body kind of yelling, because one can yell perfectly find and sound as though it's all one voice. (think for example whitney, she yelled like the best of them, but from a grounded place!)
hit me up on skype sometime (Elrathion), I can give you some tips which if you practise it you can really improve alot, cse you have a beautiful instrument.
And btw I wish I had your natural gift when I started learning how to sing! Great work for comming so far on your own!
Hope this helped ;>
