If there's one general rule about pixeling, it's CONTRAST. The colors are SO dark, and unless I missed something, it's way too dark. I'm going to give my critiques based solely on the lighting. First off, I know that it is supposed to be a night scene, so the sky is fine. However, since when is fire that "dark?" Use some brighter oranges and yellows to brighten up the fire a bit. Second, I think this has already been mentioned, but the shadow is very strange. Not only does it appear to be going in the complete opposite direction than it should (unless there is an unseen light source), but the shadow is being cast on water. Last time I checked, water reflects and does not cast shadows (unless you have a flood light over the water...). Also, if you are going to keep the shadow over the water, take into consideration your environment. The character is standing atop a dock, which I estimate is at least 2 and a half feet above the water. Right now, your shadow seems to extend straight from the top of the dock to the water, with absolutely no refraction or height difference. The shadow should drop down to the water, thus giving the illusion that the guy is actually standing on the dock. If you don't understand, go outside, stand on some stairs and observe your shadow. Thirdly, fire, believe it or not, DOES put off light. Even if light is coming from behind him, which it looks like it is, the fire will still give off some ambient light. What is ambient light? See below. See how the face is, for the most part, dark and "shadowed?" Now, look at the face...although there is not much, some light does travel "around" the face to highlight the curves of the facial structure. Still don't get it? Here's a pixel character from PixelJoint by surt. As you can see, the entire front of the character is lit...you can make out all of the muscles etc. Compare this to what you have...okay; they're for the most part the same. Both his and yours have an initial light source. Now, notice the green glow on his left (our right) side? That is ambient light. It is coming from another light source, but it does not result in the full out shading of the character. Try and do this with your character. The fire acts as the green glow does on surt's character. Lastly, the map contrasts way too much with the rest of the piece. Everything is dark dark dark, and then BOOM, light. Try bringing down the saturation of the map colors (i.e. Use more washed out yellows and oranges...picture the color you would get if you mixed yellow with a bit of grey). That should make it less prominent. I know it's the main part of the sig, but it seems to stick out a little too much for now. Well that's all I have for now. Sorry for the lengthy post.
