Can you please send me a profile picture or tell me the username? (I searched for it as RIDDLE, but the artist doesn't appear.)

try profpseud0

Yes! It's him!

Really?, both accounts poincaireofmurcourt and 044 (Riddle) are seems different in artstyles

That's strange... I just checked the character's profile and its creator says "poincaireofmurcourt" as such. I also have another character from the same creator, so I checked the other character's profile and found his account! I searched for it on Toy House as: "044" "Supposedly" they're the same person. Maybe the artist had two secondary accounts? And as for his style on the "poincaireofmurcourt" account, I don't know the reason behind that, but I'm confident it's him since when I was trying to buy both characters, I contacted the same person on Amino.

maybe because those 2 accounts focus on different things "Poincaireofmurcourt" seems focused on human design, while "044" focused on kemono stuffs, and last login record of both of them are also or coincidentally recorded 2 years, 2 months ago

Oh, I see!

Also one wonders why he inactive for almost 3 years... Is there any other way to contact him?

I don't know him, sorry. There are many people on the internet who disappear from their social media daily for personal reasons and reasons we'll never know unless they have another account, but again, I don't know any other way to contact him.

One sees, one hope he'll be back active again so one could discuss more

Hiii! Thank you so much for participating in the auction ✨ I wanted to contact you through this channel because I had a question. This is my first time charging on this page. What is "Commission" creation? Is it like a kind of conversion where you specify the payment method and then provide the character? I'm so sorry for bothering you with that. 😓
