Here I made an edit for you gem. My words of advice are.. First: When choosing your colors, dont choose colors that are so close together, I saw atleast 4 colors in your pallete which I could barely tell a difference in. Second: When shading, Try choosing a more valid light source (Eg: mine is coming from the left of the sword). And Lastly: Another pointer on your shading.. When I looked at your sword, the pixels seemed wayyy too cluttered, Almost as if you randomly threw the pixels anywhere you thought they could go. If you did so, Try not to do that, You should always have control of each pixel you place, because in the end it will effect the outcome of your image.
But anyways: take a look at mine and Em's edit.. And if need be you can use my edit on your server.
