I think you missed my points, ShunNakamura.

The Rogue one is not so much better because it is still just part of an image. If the rogue ended at the knees, it would have been a good idea to either construct his legs and use him as you did, or scrap the idea and use the rogue in a more contained signature. A transparent signature is too open for an incomplete image. What you have fits more into a banner rather than just standing alone.

As for the cowgirl signature...no, you are missing the other half of the moon. Cutting out half of an image looks strange and out of place:

You can see what I'm saying, yes? A full, uncut moon is best.

The En Garde one still misses a bit. An image to illustrate the advice:

The walls still do not match in heights; the lighting on the walls are uneven and do not match up, not by any angle. If the light is coming from the front of the image, the darker tones of the side walls would end at the top of the darker brown on the back wall. Also, the shadows of the text and the character would also stretch out behind them, rather than at any angle. Consistency goes a long way.
