Nah I don't like it
If it's to use as a title of sections I think you would be better with simple and cute that looks the more professional as possible.
The objective of pics with letters is to give some shine to the sections so people know easy where they're and not make it look that the pic is there so it doesn't become a boredom section and impregnate with tons of colours.
For me there is too many figures[ro monsters] with the letters because having more doesn't mean better.
Also, you would be better with some less used fonts then the standard ones and make the titles more unique instead of the usual ones[and yes, I know that having something "unique" is hard with ro monsters but still, there is some touches that can be given here and there to look less usual].
5 minutes example:

Having a standard format is fine but having the same aspect every single section[as having a ton of monsters being used all the time and just change the letters when should be the opposite] makes it be like the sections all mean the same when that's a lie.
