Is my lil guy good in here?

Hi chat this is my first time with a string of pearls and I'm scared because I've heard so many conflicting things. I bought this beautiful guy yesterday and I really really really wanna take good care of it. The pot has good drainage, it's clay. I kept most of the roots in the nursery soil it came in and put my succulent custom blend at the bottom (all my succulents love it it drains well). Miss pearl over here is about 1 foot from the nearest window facing west so it doesn't get too much direct sunlight but just enough indirect. But I'm worried about the pot size. Is it too small? Should I replace all of the soil with the succulent mix? Some dirt is poking out at the top and that just has me worried it's too squished in the current pot. Any advice would be so appreciated!
