Here’s my starting process to laying down color on this Sinestro Sketch Cover. Since the DC Sketch Cover surface takes markers well I’ll use a combination technique of Copic and Liquitex. After the base background is put down, I’ll mask off the logo and Sinestro with tracing paper and painter tape. The star field is achieved with Liquitex Free Style Splatter Brush. After the splatter paint is dry I’ll add the glow to various splatters along with burst to complete the feel of space.
