My sister is expecting a baby boy in September, and asked me to draw some animated characters for the nursery. I drew a stork with a baby which sparked the idea of a figurine of the stork delivering the baby boy or girl to their new parent(s)! I hope you like the design, sorry for the lack of details! The stork will have a base to stand on and buyers will have a choice of weither the figure is for a baby girl (pink) or a baby boy (blue)!
And Samotage has a point, but it might work as a plush in the nursery room. Maybe as a gift for the baby: it could be personalized.
My problem with this is I have trouble seeing an audience for it. Sure you can give it to expectant parents, but in my opinion it's not something they'd put on their desk at work or anything once the baby has been born. The only thing I can see them doing with it is putting it in the baby's room.
And in that case, I suggest picking more pastel colors. You've got pretty vibrant ones, but babies' rooms are always decorated with soft colors, so you'd want this to match.
