I think the overall idea/look of Vy's burning City Hall picture is great. I also really like the NCsoft fireballs.
For the picture with the black silhouette, unfortunately the first thing it made me think of was "blackface". I also think the figure's a bit creepy, but maybe that's just me.
I can see where the "angry Asian man" might be received by some as racist. I think it would help a lot if you could actually use Kim Taek-Jin's face, rather than using a generic Asian man in his place. Could that be done without compromising the feel of the picture?
Though I actually kinda like Godzilla, too.
