Complete Form for various data

I need to create a form to be filled by users; the form should contain areas to add text and other areas to add photos, with a selection and dropdown lists.

The form should have restrictions on the word count (a counter of the total words written and the remaining to reach the limit should exist on each tab beside the head of the tab or at the end after the final line), the photo size, and the format.

I have tried to make a sample, and this is my best (edit pass is: 123):

I can't remove the highlighting on the text area and can't control or keep the document font and format when pasting from an external source (the current format is corrupted by pasting), and I can't even add the written words counter.

Any advice is appreciated in this regard ...
