Comparing Forms Inputs and Responses

I am currently in the process of designing the UI for a "compare" tool that allows a user to compare forms that someone filled out. In this example, a person has filled out a form online. Their form could be denied for various reasons, so they must fill out a second form. From there, the person reviewing the form would need to be able to see both forms to see what changed. However, this type of comparison is done on an object-to-object basis. Meaning they are not comparing the entire form, but rather, a specific input field.

Perhaps a user typed in a response in a textarea and in their second response, they updated the textarea with more details. The person reviewing the form should be able to see the responses and be able to clearly compare the two responses in the textarea.

Any thoughts or ideas on how this could look or perhaps other web applications that have done something like this?
