So hard to believe it’s your first. I’d love an edit. Here are my character details:
Body: Light
Brow: Seductive Round
Hair: Layered Hair, Black (It would be great if you could make it a little shorter tho!)
Eyes: Upturned Bold, Black
Face: Diamond
Nose: Roman
Lips: Classic, Orange Crush
Clothes: Light Teal Beach Day Romper
As for the pose, theme and background, absolutely anything is fine!
Thank you so much!
