Not sure I like what's happened to the leaves in this, no texture. It's a nice enough composition but a little on the boring side. Overcast daylight could be the culprit?
Intrigues me for its take on the challenge, but beyond finding Waldo, I can't find much else going on here. The greens are okay, but a bit more contrast and perhaps even more saturation, might have made this call more to me.
This shot is a bit "bland" in composition and color. There isn't a lot to compel the viewer to stay with the picture. Maybe if it were a bit brighter and in bw it might have more redeeming features.
