Some of the perspective/angles seem a little off, and as mentioned before, his head seems... odd. Another thing to note is that you may want to give the lines a much bolder, finished feel, either by making them thicker and/or using black or darker paint/pencil/ink/coloured pencils.

If you were to improve the face and make the lines much bolder, and his stance a little more natural looking, it would be a well done picture. Just a bit more of the colours you have already used, some darker ones here and there, an adjustment to the face and right leg of his, and I do dare say, he would be a mighty fine Edgar.
