Memory Overwritten - 3D Render Artwork - Pwnisher 3D Overgrown Challenge

My 3D rendering Artwork of an overgrown retired robot. The robot my friend lend me long time ago using Maya. The trees & plants was created using SpeedTree. The vines on the robot body was created in 3ds Max using Ivy Generator plugin. I use Arnold render to render the whole scene, the outline in the render was created using Arnold AiToon shader, I want to make it have a feeling of the anime/cartoon. This was inspired by the Bastion from the video game Overwatch, I used their artwork to inspire the lighting, color,... The effects was added in Photoshop.
