Poster work & Question about Halloween costume (Patreon)

This picture was made for a poster! so it's colored of CMYKThe cell phone in NOONA's hand has illustrations of Merchandises that actually sold.There are two pictures on the phone.One is the Chibi version of Noona. Personally, I think it's came out lovely hehehe...:3I love cute things, so I really like to draw small SD characters like this.Other is this one!When I first opened the commission, a friend who liked NOONA since the beginning, they wanted to have a couple picture with her. So they've been designing their OC for commissions.The concept of the painting was a cute setting that a white wolf friend asked NOONA for a couple's hand heart, but she changed it to thumb because she was embarrassed, so it was a really fun drawing and I was moved by the heart of my friend who had produced the character their self for this art.The commission work at that time was this picture.Personally, I really liked this painting, so I added retouching and made it into letter merch with my friend's permission^.^The next following revelation are an illustration psd file and a color speed painting video of a poster picture, which is an Omega milk tier reward. Will be uploaded tomorrow :3Ps.hmm... now I'm thinking about what kind of costume I should dress NOONA for the upcoming Halloween. what halloween costume should i draw her with?Plz feel free to comment on the costume you want to see. I will refer to it! of course, you can send it to Discord :3 **I decided to gather opinions and proceed with Bat/Demon Costume! Thank you for your message ^.^
