The new section header uses an all-caps title with a trailing colon ("## DEMO:") which is inconsistent with the rest of the README headings (e.g., "## Comportamento atual" without colon/case). Consider using the same heading style for consistency (e.g., "## Demo" / "## Demonstração").

Suggested change

	## DEMO:
	## Demo

All three images use the generic alt text "Image", which isn’t descriptive for screen readers and reduces accessibility. Please replace these with meaningful alt text that describes what each screenshot shows (e.g., dashboard view, export results, etc.).

Using raw HTML tags with explicit width/height attributes adds noise to the README and makes future edits harder; Markdown image syntax is typically simpler and renders well on GitHub. Consider switching to standard Markdown images (and omit fixed dimensions unless there’s a specific reason to keep them).
