Hey! This is a really nice illustration so far! If the windows are meant to be glowing, the first thing you should do is darken the characters. Keep in mind that if the light source is behind them, any elements in front of that light will be mostly in shadow, since we're not seeing their illuminated side. On top of that, you can increase the brightness coming from the windows. This will create a much stronger "dark against light" contrast, rather than the "light against light" situation you had before. You could also add a bit of light along parts of the characters' silhouettes, not the entire outline, just a few areas where the light would naturally catch the edges. And to create even more contrast, consider giving the characters cooler tones while keeping the background in warmer colors. | Artwod Feedback
