Here's some futzing around I did with Megaman since that seems to be the flavor of the week. ;P
It's my own retooling of his original design with a bit of the Wily Wars sprite thrown in.
And that is my interpretation of an 8-bit X that I did partially 'cause I didn't like the ones I've seen around and for scaling purposes against Rock.
And this is an edit I made of the Archie Comics sprite of Timeman in 8-bit style.
I feel like I should tweak the right arm (left from your view).
Maybe move it up a pixel or two so it doesn't look like it's as long at the elbow as his whole other arm.
And to bring things back to CV...
This is a mock up of the title screen used in the Akumajou Dracula X translation project for the little mini game thing if you don't have the right hu-card inserted:
And here are the actual graphics inserted into the game before the palette was corrected:
EDIT:
Here's that little adjustment to Timeman I mentioned I should do.
