How should i display a 'non checked' checkbox?

Question

At the moment i'm making a redesign for a page where the customer can fill in their preferences for receiving a newsletter.

There are four options that can be selected and on the enterance of the page they are all 'checked'.

If the visitor deselect an option, than there will appear a red cross is the checkbox

Is it a good idea to keep these form of deselection feedback in the new design, or should i let the box empty if it is not selected?

Answer 1

An deselected checkbox is an empty checkbox. Leaving the red cross may indicate that the check box remains selected.
