Hey there! So cool character! :D The thing I'd do is to adjust the values. I made the BG a bit clearer so I could make the character darker; this way, the silhouette would be more interesting. Notice that I also reduced the saturation of the shadows to avoid having everything too saturated. I deleted the glow from the hand since it was somehow distracting for me; instead, I painted the glow in the eyes and eyebrows to create more contrast in that area. Hope this helps!
