Wow.... I don't know what it is about the position, but i really really like it ^.^ The position looks very natural and just makes you want to look at the picture more. I really like how you position your drawings they are always very ....natural is not exactly the word. Interesting? I dunno, but they always make me look at the pic longer. And I love the tail ^.^ I have tried (and failed) to draw Mermaid like creatures and the tail always comes out funky... And as always i love how you draw the body, Though the arm furthest away from the viewer looks kinda funky (is that the one you were refering to?) And her hair is very nice, and I applaud your ability to draw faces, cause i lose in that department...(can't draw the stupid noses....)

Overall this pic is very nice, I like it, and i am kinda glad it doesn't have a background, i think the picture would look better without one.. At least in My opinion.

Ok I'll stop rambling now ^.^;;;
