Grading system/score with skulls?!

I’m new here, so please forgive me if asking something stupid or something that has been debatted before ??

1. I have this grading/score system that I give each album at the end of my review, it ranges from 0 to 6 ‘stars’, but I want to change it to look more ‘metal’ like ex. this one https://www.metalunderground.com/reviews/details.cfm?releaseid=5058 please look at his ‘skull score system’, or even this one: https://www.heavymetal.dk/releases_view.php?id=4234 Is it a plugin that I can download somewhere; not maybe exactly the same but one with smaller skulls or similar would help too ??
2. Second thing is almost similar, or in the same category, to the first one; my now cursor looks like a hand (ordinary) but I want to change it to look like ‘horns-up’ ex. here: https://www.metalzone.dk/index.php?side=expandcd&id=2019
What can I do to change these two things. Please help me by providing the right link or a short guide. Thanx in advance.
