Hello people!
To be quite straight forward, I'm new to this forum and still a newbie at pixel art, so I apologise if after reading the rules I still end up messing something up about my post.

Here is one character I've been working on "Tiberius Defender of Troy".
I have been struggling on this one for several reasons:

• First colours, I had a hard time picking a skin colour which was zombie-ish
• Second, I also struggled with the helmet shading, that is avoiding the same shading as skin, so that it looks metallic
• Finally, the only feedback I had received was that my piece was too noisy so I'll include the image how it was before
  I worked on that, at the end of the post, so that you can get an idea

Any criticism and commentary is very welcome, and I thank you in advance if you do comment!

Here is my piece as it is now:

And here it is before I worked on the noise (this is a backup file so pardon me if the background isn't see-through):

EDIT: The img tag doesn't seem to work for me, my apologies, hence the imgur links..
"Image Host guide" is down, imgur doesn't seem compatible, what do you guys use as image host?
