Perhaps these pictures could need a slight edition for improving the lighting or the contours. I have attempted to improve them from the original versions but I didn´t find those attempt to be very convincing in my eyes.

So, if the alternative doesn´t even offer anything remotely interesting, then it´s better to leave them as they are. Save Spike, these are all the characters that you see in the movie scenes (and the original ones that the artists drew in the first place)
