The flag is the much more compelling image, imo. For me, the texture in the bricks is incidental to the mural, whereas in the flag it is an integral to the wind "whipping" the flag and "rippling" the fabric as part of the image's storyline.
One thing about the WA, given the chose between a compelling image that "complies" with the theme and one that is "not so compelling" but is very demonstrative of the theme ... it can go either way. But when you combine both compelling and demonstrative (and clever/unique when you can) it makes for a winning image (no matter the actual voting).
Micro-nit ... if you have some more real estate above the star, I'd consider cropping so that the right hand star is fully revealed. Diggin' the corner usage / leading & implied lines.
Nice job, I see the flag as "serious competition" ... to which I'm gonna have to get busy and "up my game" for my entry this week.
The brick wall, not so much.
