Beautiful 3D render, but the tree is terribly short from the perspective you've made, and the cane itself, which is VERY realistic looking, looks too short for it's huge size in comparison to the miniature tree. Grandma must be a midget...

Check out a "real world" cane that is similar:

Really nice work, it just needs a tiny bit of adjustment.

"Grandma must be a midget" LOL poor grandma. Yes, you're right, it needs some adjustment, thank you!
Edit: adjustments done

Looks great, my grandmother was only 4'9" she could have use d it. LOL Nice edit.

I didn't see it before, but it looks great now. Very good concept and render, author. Love the symbolism of the sunset, too.

Great correction, it looks very realistic for use "in the sunset of our lives..." Well done, author!
