Trying to get back to pixelling (despite never being very good at it in the first place):

I'd like to add some definition to the face but have been unable to do so while keeping its appearance halfway decent.
Looking good. I think the head is bit small. So you can make it a bit bigger and bring some details to it on the way.
Trim both body and upper feet shorter by 2 or 3 pixels.
And add 1 or 2 pixels to head height. Forehead needs definetly 1 extra y pixel to make character look smarter and more likeable.
