Note: You are asking what is wrong with it so I am going to lay everything that I find wrong with it down. Don\'t hate me for doing what you asked for.
-The photo is too dark.
-The nipple Dynamite piercing thing straight up looks terrible.
-Your paint was too thick
-The flab of skin around his neck is way too big. The fact that is it GS is too obvious.
-Like you said.... The base is poo
-Is that an egg at the end of the blade in the left hand?... Not sure what the little white ball is.
-The dark lines that seperate the shoulders from the body are too dark, it looks like his arms are detachable.
-The entire miniature needs more attention to chiaroscuro, you are missing the highlights. You do seem to have the middle ground and darks though. Also, the blending of the chiaroscuro could use more attention.
-Where are his eyes?
-When you paint flames, the whites are in the recesses and the dark browns are the highlights... pretend you are shading the flame naturally, just in reverse order of colors. You are close... but they are not convincing to me.
-You used inks and you made it too obvious that you did.
Alright.... There\'s a good start. Work on those then come back and ask again. Also, keep in mind that there are a lot of things that you did right, but your post wasn\'t asking for praise, it was asking for the nitty gritty.
Best of luck with your Ogres.
