Hey!
I just want to let you know I made a cupcake factory about one year ago!
Cupcake Factory by Ombreuse on deviantART
I'm still improving, and I need to add more stuff, but you can have fun with this one!
You're able to use your cupcake as you want, for non commercial purpose only and if you don't claim it as your own.
Hope you'll have fun :)
