Bordo,
I really like #216 and what you did with the exclamation mark. Can you play with our color scheme and integrate some of the colors? Specifically, the door: the black and green makes it stand out, but could you try some colors other than black?
Also, could you provide both black AND white backgrounds for your designs? You're talented so I appreciate being able to see how they would look in different mediums.
Cheers!
