Not a bit. You can have art for your own enjoyment, it's allowed!

I am always in favor of getting art for whatever reason.

Totally worth it.

Would it make you happy? Can you reasonably afford it? If so, that’s all the justification you need.

I think that would be very cool - the original (or nice print) framed even. Ephemera is a great way to express what you love and the joy it brings you.

do it for yourself, not for anyone else. This is fine and up nobody's ass.

do it! Totally worth it!

my guy, I commissioned art for my D&D character, and he's barely even a bulleted list. go absolutely go nuts

My own "should I buy A Thing" rubric basically boils down to "can I afford it, do I have room for it, do I want it enough to go to the effort of sourcing it?" - I don't consider "do I need it for practical purposes" or "what will others think about the relative importance/relevance" as important factors.

Never a bad time to commission artists.

Can you afford it? Would it make you happy?

Then do it. It's that simple.

Life is too short to not celebrate your wins, especially with dope art.

You should do it because it will be part of your life, and part of your story's.
