I think a good way to look at it is to decide what you want to build your dio around. Pick what you want to be as a focus of your dio; a tank, soldier building, etc. and build around it.
Say you have a jeep, and a crouching soldier. Where are they? Why is the soldier crouching? Is he looking at something on the ground? Is he looking at the jeep? Is he ducking from enemy fire?
If there's enemy fire, where is it coming from? Are there any allies of the crouching soldier running for cover?
This could go on, but it leads to what will become a solid dio idea. One of the most important things about a dio is
that the viewer needs to know whats happening . If viewers can see a crouching soldier looking at a jeep's fully inflated tire, they'll wonder what's going on. But if the soldier is looking at a
flat tire....
See what I mean?
