Hi, my name is Peter and I'm the art director of "Sparky Marky" and "Do you see Sparky?" projects. Art team makes every effort for the projects to look original and interesting. We create all the objects manually according to our art style. But we made a mistake. There is one tree that was left from the earliest version of the project and it was made not by us. I apologize. We have already made changes and updated the visuals of the project. You can find my concept below. In the future all these trees will get to Amber Spark. Hope it will be cool!
