Thanks for the input.  I think I know how I got so many colors in there.  I'll have to keep that in mind next time.

its a nice composition, but i need you to stop right there. there are a couple of basic elements that you should be aware when making pixel art. one of the most basic elements  is the color conservation and the efective use of them in order to get the best result with the less amount posible. your image has over 254 colors, and while thats almost the max that could be somehow "allowed" for a pixel, you'll notice that there are quite a lot of them that are almost identical, oly differentiated by 1 or 2 values in its RGB scale. the idea is basically that instead of using a new color for every single element in the image, you could reuse the ones you already have, maximicing the use of things such as hue, contrast, etc. its easier than it sounds, and its not only a fancy element, but its intended to help you develop a better understanding of how colors can be used and eventually willl lead you to be able to used more interesting combinations. give this thread a read to get a more in deep explanation.
