Fixing Some Problems

I put the original image on a light table and trace-sketched new versions of each of the characters. As you can see the poses are still off-balance and forced but the characters look better. (Note: I didn't put in any more of the costume details than were absolutely necessary. These can be added later and are of minor importance.) These images are very rough and would only be used as guides to fix some problems on the original when doing a cleaner drawing.

Rabby

Of all the characters, Rabby needed the most work. (This is not because the others were better but because there is more of Rabby visible.) I started by fixing her head, particularly the chin line and face.

The chin line defines the character's head, which is the most important feature. This is the most important line in the image and if the artist does this badly everything else will suffer.

The body pose is no good and the form is strange and fat. The worst part was the arm positioning and the shoulders. I dropped the shoulders and redrew her torso (note the addition of the particularly feminine parts that seem to have been left off in the original) and vest. In the original the orientation of her belt seems to imply that she's thrusting her crotch at the camera, which is not what we want in this image so I changed the belt angle. I cleaned up her hair and made it look softer and made the curves deeper to accentuate the feminine qualities.
Even with the changes, I'm not happy with the hands because the right one doesn't have good foreshortening and the left is in a totally unnatural position.

Patty

Rumy

Lumy was pretty much a lost cause. She was so close to Rabby that they must have been sharing some body parts. She is way out of proportion and her head was larger than Patty's torso. The artist must not have liked this character very much as she's the sketchiest and least finished. This is a common problem with fan art. People only want to draw the characters they like and pay little attention to the others. This is why most fans drop out of animation school and companies—for the first couple years all you draw is things that you don't care about like shoes, doorknobs, background characters, bubbling stewpots, dead rats and such. If you treat each character with respect then you will create a much better image!

The Conclusion

In truth, there's no real way to save this image by just sketching fixes. Because of the pose and perspective problems the whole thing should be redone. Assuming that some fictional art director wanted a basic setup the way it is here I came up with this rough, based on a printout of a wireframe version of the Poser scene. I didn't let the 3D image dictate every part of the new image. Note the line strength differences.

A primary function of art and thought is to liberate the individual from the tyranny of his culture in the environmental sense and to permit him to stand beyond it in an autonomy of perception and judgment. —Lionel Trilling
