This is an unnamed character claiming a ring after having chased down his target.
The speech bubble is in Japanese: "Well well well.. Thank you very much!~"
If you zoom in, you'll notice that the coloring is 'halftone dots' gradients. I think the labour was worth it. I was experimenting with this for the first time, so it took quite long (8hrs+). I can cut my time to half now that I'm used to it.
I'm currently building a world concept around this illustration. I'll post some character line-ups soon. I imagine it as an RPG franchise for popular handheld gaming devices and online PC platforms, so I'll fashion some screenshots for visualization as well.
