Nice normals depend on whoever is looking. Some people like a very reduced pattern (basically where the alien heads dont have eyes, and a lot of times the heads will form together to give it a Long alien head) Here's a post I have about them when I found one at petco that I almost got but didn't due to well...it being a petco!

There's also some examples of other normals that are reduced pattern or "banded"
Then there's blushing and flames.
Personally the more blushing and flames a BP has, the more I adore it! Flames and blushing are almost the same thing, the only difference is placement. Blushing is on the back, flames come up the sides. here's a link to the hunters guide to yellow bellies. Yellow bellies look like normals with some small differences. But in the guide it shows exactly what flames and blushing is.

Last but not least what will help some, look at some of the other hunters guides. He shows how you can tell the difference between a couple different type of ball pythons, some of which are easily confused with normals.

Like I said, how pretty you think she is, depends on what you like. Some people like really wacky patterns and try and breed with other balls that have wacky patterns, some people like reduced and try and breed with other reduced. Some like a lot of spots, some dont. Just depends on what you like.
