It's best to let the user determine how they will view the webpage. Headings and list elements are nested properly. The levels of headings should be used to convey the organization of the document, and shouldn't be used simply because they display text bigger. This also applies to nesting ordered and unordered lists. High flashing rates can trigger seizures, and moving text presents reading or tracking difficulty for users with poor vision.
Text used as a graphic is read improperly by a screen reader.
Replace the text graphic with an actual image, making sure that you use an ALT tag to describe that graphic to visually disabled users. All images have ALT tags. Make sure that the ALT tags are descriptive enough to provide an adequate description for a screen-reader. If the image is important enough in content to merit a long description, consider adding a link next to the image that goes to a description, or creating a text-only version of the website. Try not to use image maps.
