That's a pity - and not allowed I think. But other than that this is a really nice piece, well done!
I love the sudden dark depth of the trees, so good.
wow, hand pixeled or not it still looks awesome
the water reflection is so awesome to looks at!
IMHO it is fake, it looks too computer generated, and the 201 colour count isn't boding too well for you
Saying you did something pixel by pixel doesn't really mean you didn't use filters or tools like soften or slice. All it tells us is that you didn't shrink down a digital painting. In it's purest form (the one generally celebrated here), the artists tend to use nothing more than pencil, line, circle, and the selection tools, reusing colors to keep them at a minimum.
IMO, the dither on the sky does not look hand-done. The colors are too gradual and the patterns scream indexed radial gradient.
it's completely pixel by pixel.
