indeed. all elements of the image need to be 100% hand pixelled.
as for the pixelled part of the image: I don't know that the greyish color works well with those blues on the armor. I'm also confused as to what color his tail is, as you have orange/purple/green on a continuum.
I just fooled around with what i thought were desert, sandy colors...grey looked a bit right...but ill get better at my art, just a beginner :/
