? about leather

[cityreefer]

Morning
wonder about my leather coral( finger leather), i have had this coral for just under a year and it was damaged in my recent move to the big city. its been doing good but wondering if there is anything i could be doing to help it get back to what it was before.
i would say its about half the size as it use to be, this was such a nice coral i am sad that it got damaged.

any help/ ideas would be great
