Is it really that big? Maybe you should save it with different editor.

Also, if you're using GIMP, try setting the image mode to indexed.

You are right, resubmitted it original size. Still don't know how can I make the preview better, full picture is a bit over 10k which is not liked by the site

Nice, but there's no need to post it zoomed.

Very detailed little pixel, I like it.

It's a coincidence, I think :-)

The colors reminds me of old japanese art.
