Titan Oil Painting Series

I'm going to create 100 Titan oil paintings, then most likely create one giant one with every character at the end. I think I'll give away each piece live on stream. Titan mainly exists digitally right now. Time to bring an entire family to life.
This is the brown underpainting for Titan #1. And one of my first ever oil paintings.
Okay, now we're ready for some color. I can definitely see a lot of places where I can improve, but it's a big leap forward from my last piece. The background/edges really need to be cleaned up and smoothed out. Honestly that entire background area could user another pass. I've spent enough time in the greys for now, time to really start making Titan pop!
Here's the rough sketch for "Titan 2". Maybe do another tracing layer, then transfer to canvas? Or just go for it :P.
Progress in the greys on Titan 2. About ready for some glazes of color!
