I like it!
With romance books, I see more than this. And as a POC woman, I LOVE how you show the diversity in your characters. I don't believe in the, "let your readers decide how folks look" because authors used to do that and readers always assume someone is white. The default is white and if you don't give some description of different characters who are diverse, no one will know. I also don't get the argument of "alienating people" with photos of characters when book covers have photos of people all the time. What's the difference between a picture and someone describing a character? If I say my character has curly black hair and ocean-blue eyes, what difference does it make if you see a picture of her or not? I DESCRIBED what she is, anyway. If anyone is alienated because of the way characters look, well then they might just not wanna read books with certain characters. And that's all I'll say about that. I don't see how an author showing their characters is a bad thing. I think it will get you MORE readers.
And readers have often said they prefer to know what the characters look like clearly and up front. I know I do. A character's description is important and makes a character three-dimensional.
I'm looking at it from MY lens. Others might feel differently but as person of color, who values seeing people like me in all types of books, this representation is super important and I like to see people who look like me in books, and I appreciate it. Call me crazy.
As for the design of it, some might say it is too much then some won't. You can't please everyone. Do YOU like it? That's what important. But I definitely think seeing your characters will make more people wanna buy it instead of not.
Good luck with the book!
