How to make use of someone's quote or image in my LinkedIn post (and mention him/her)?

I would like to repost a cartoon via link of a well-known cartoonist in my LinkedIn post and make a short comment based on that. I’d like to say that I really admire his work, because he/she can illustrate so well the reality-and I probably I can’t!-and put down my thoughts about this situation in the drawing. I don’t like to look offensive though and of course I will mention (@) the name. So here’s what I was thinking to be as the opening sentence of the post:
"I wish I could be as good cartoonists as "@xxx" when it comes to illustrating reality, but i am not. So I would like to take the chance and make a worthwhile use of his."
