I agree with all the advice everyone has given you so far but I don't really understand what you were trying to do with this tag.
It looked like you used a render from this stock.
Then you put it on top of a fall road stock.
Something similar to this.
Then you turned it black and white and spammed a random brush and warning sign.
For the other versions you did exactly as you said.
The render, as said before, has no flow. Plus the background doesn't lend it self to create flow. If the render has no flow and the stock/background has no flow you will have a very difficult time creating flow.
Here are two examples of good flow. The first is one of Kraq's tags and the second is one of mine.

The flow in this tag starts from the tiger and flows outwards with the lightning type effects. This type of flow starts you at the focal and brings you through the rest of the tag.

The flow in this tag can be seen two different ways. Some may start at the focal and follow the arrows out. Some may start at the outsides and work in toward the focal.
Both those types of flow drag the viewer through the piece very smoothly.
Here is your tag.

The "flow" in this tag is all over the place. All the brushes you used draws the viewer away from the focal. As you can see the focal as no flow and the warning brush causes some conflict. The triangle point jams into the flow of the other brushes. Also the warning brush sticks out a lot and many times when I look at this tag I see the warning sign first.
For your next few tags I think it would be best if you worked on flow. Try to use more appropriate brushes and renders/stocks with some flow already in them.
Hopefully this helps.
