I'm soooo sorry for this but I don't think it's good at all...

first of all the red borderish thing is really out of place, and it's not that good and doesn't even go all the way to the right or all the way down (not that it really has to but the right is just empty and it's not like there is a concept that would make it fit like for example White_Dove who leaves empty spaces at sides, at least there is a conept there because she fills them with at least a solid color and doesn't just leave the image as it is)
second it's really messy, the image, and you can't really see the person, mostly the trees and the house in the back... it's not that good and it doesn't even look blended at all...
third the text NEEDS effects, and the white doesn't fit just like that, perhaps if you blended more it could work with the white but certainly not just like that...
and also in the bottom right kind of area there's something blue which clashes veeery much with the rest...

you've done better sigs... and although I get that there might be alot of feeling involved in making this one I don't think that it shows at all, because the way the sig is made it doesn't even look like you cared about it, more like something you just threw together as if it was just something meaningless...

I really think that if you want to continue and get better you should ask for advice, I don't use PS but you can still ask for advice about things in progress or you can ask others, I'm sure they'd help out and give you some tips and advice if you just asked...

I know this sounds really harsh and believe me when I say it's nothing personal at all, I'm just telling you what I think, you might disagree all you want but at least that was my opinions, it's better to give advice than to lie and only say stuff people want to hear...

I'm sorry...
