nice motive, but as undefined/sloppy as it is as the moment and with 398 colors it's not pixel art in my book.
edit: also, checking your gallery, the improvement between your last piece and this one is suspiciously big, so i googled a minute... you should post your references!
mmm... ppl... maybe i'm saying something wrong... but, why this is not good? i've read your comments...
also if there are a lot of colors and realistic gradients a pixel-art work is still a pixel-art work... a know a little this guy... in other place he goes around saying to the one that talk about their job as pixel-art really true things... that pixel-art contains only the project entirely made whit PAINT, no other stuff, he takes this thing really seriusly... if you use any kinda of digital antialyasing or other tecnic you're NOT a pixelartist... so, a man like him XD so hard about this kinda of thing... can't post a fake talking about him as an official pixel-art work... it must be real don't you think? o_o
i can't garanty for him XD i don't know how much a comment of a new one can be considered... but i'm sure about the autenticity of this work ^.^ (anyway i saw other work really better and more digital-like than this... if those are pixel-art work, and surely they are.. this must be too...)
stop me if i'm saying something wrong... and i'm sorry if it's so ^.^
