Manupix:

thanks for the tutorial, I needed a lot. I'll fix tonight and will go up again. more ... did not know there was a help forum.
thanks and hope to keep up pixels much better every day.

Good one, I love the face. Nice colors.

I can't decide if we are seeing the back or front of his body. Also the way the left forearm is hidden makes it look like he doesn't have one.

Beware of banding!

Sure here's a quick edit.

Notice the difference in the smoothness overall and apply it to other jagged lines as well.

HELLO GECIMEN.
I DO NOT SPEAK ENGLISH, ALSO I DO NOT WORK VERY WELL I AM VERY NOOB AA EN ESO.
I'd appreciate IF I COULD HELP WITH THAT OF AA. Excuse my bad English and THANK YOU.

Overall good design. The shirt seems too dirty and the inner AA on the right side is done with light colors instead of dark, which creates a very jaggy line art. The skin colors are too desaturated. I think if you give this piece 5 more minutes it'll get to where it deserves to be.

It is very well made (= to me it was pleasant 

Love it. Though it makes no sense to call him 'the'.
