It should have plot, nice backgrounds, interesting characters, and some humor. The reader should WANT to know what happens next. The panels should be laid out in a pleasing fashion...oh, you get the idea. Here is what I am recommending:

Far Flung is the story of a little furry guy who leaves home to seek adventure and everything goes terribly wrong. He lives in a magic fantasy land but strangely, this is not all rainbows and pixies but you have to read it to learn more. The artist and writer is Poinko who has worked on furry comics for years and I got to talk to him at the Texas Furry Fiesta so he has been vetted for you ;)

Anyhow, enjoy the story!
