Croping and Editing Images

[Erine81981]

I need some help. I know how to do crops and edits but i'm not that very good. I would love to have someone who is really good at croping images and making them clear/sharper and more well rounded then jagged. I know there are some really good edit people here becuase of the Muppet Wiki.

If there is anyone who can help me. Please just leave a post. Thanks.
