Hi @gohba.handcrafts Interesting your post.

Your carving is wood. Wood can split, crack, rot, fade, burn and/or be attacked by insects. Putting a little thought into where and how it's displayed can help your carving to last years longer.

Don't set your carving directly onto soil or grass. A pad of concrete, gravel or paving stones is better and will help protect the base from water and insect damage.

Heat from either harsh sunshine or even the household heat (indoors) will dry the wood quickly which causes additional cracking. Avoid these when possible or be prepared to renew the finish more frequently.

Well, it means your carving is going to crack. It's part of the natural process so you might as well enjoy it.

I'm wishing you success and growth, and happiness.
Have a nice night
A hug
