Usually I do all my work strictly on the paper, from first pencil marks to final brush stroke. But, in order to make more magic more better, I'm learning a bit of photoshop! This firelit night scene looks pretty good, but how about some more glow?

First image is the scan, after color correction. The second is with the glow clarified. The third has flames lightened up. The fourth is a layer with sparks and glowing.
