This is my Dark Souls Character. For now I would consider it finished, but if you have ideas on how to improve it, I will go back to it.

You're not using a mouse to paint are you? Pretty much all of your edges are too hard if you're going for a painted look(maybe you intended cel-shading though). Also, I think your light direction could be made more clear, this is a bit spotty.

I painted up some steel just to show how the reflections work:

Notice the strongest reflections and light come clearly from the top left. Even if this was chrome, this relationship between lit side and shadow side needs to be maintained.

Oh man, totally right. I will have to go over that again. Didnt even realize how much improvement is possible there.

What I did is actually too clean and airbrushy tbh, but definitely being organized with your light and shadow will go a long way in making those forms feel 3 dimensional.

I think you need to work on color choices. I know dark souls has a dark and unsaturated palette but that doesn't mean lack of color. If you color pick from a screenshot of the game you will see that there is color even in the things that look like a certain color(e.g. grey). What I am trying to say is the armor should not stay grey. If you have the armor (or anything) painted in pure grey and then color other things in the image it looks like an unfinished colorization of a black and white image.

On another note, dose your character have telekinesis? Just wondering because it looks like that shield is just floating there without him holding it.

I personally feel that the orientation of the torso doesn't flow well with that of the head. The left arm blends in with the chest. It looks very unclear. You can work on the lines a little. The colors too. I like the concept, it looks cool and you can make it look cooler, I'm sure!

Oh, it's a very cool shield! it has two handles to hold it with your arm horizontally and it also has one handle to hold it vertically.
