This is a very good start for a pixelart piece. I don't know the reason why, but while it looks like the picture should have a handful of colours in the palette, the Image Specs Tool says there are over a thousand colours, lots of which seem to serve the same purpose as one another. If you could find out why that's the case and vastly reduce the number of colours while keeping the readability, I'd be happy to push this submission through.
This piece got over 1000 colors in it, it will need to be cleaned up a bit before we can accept it to the gallery.
Stunning composition.
