The truth is that climate elements its a combination of luck and persistence. But sometimes the second is not possible.

Yes, the sun rays are the point of interest.

I think two things can be done in this situation.

1. Some enhancement in post pro.

This is a typical example where tone mapping helps to add drama. (I overdid the effect. It is only to illustrate the point)

2. Framing

But if we go back to the shot itself, we have a similar case (where I made this recommendation) the framing is not optimal. So you can benefit from the rule of thirds.

We have a forced crop. Probably this works for some editorial purpose but feels in my opinion forced.*

Original:

If these rays were framed a bit different they pull more protagonism.

Rule of thirds and a 16:9 crop:

*An explanation about forced crop. The first mountain is also a point of interest.

The mountain on the right has some weight. Add that to the fact that the rays are on the right this makes me the photo is a bit unbalanced.

I will assume that the initial photo was a proportion 3:2, so there is a chance something else is below the crop, where potentially the landscape could "rest" to make the overall image more relaxing. Probably yes, probably not.

But let's say the 3:2 proportion was not the case. Simply following the horizontal composition, in this case, the rule of thirds, the horizontal proportion looks cropped to the right. There is a chance there was something interesting happening on the right. Probably yes, probably not.

In both cases, bottom and right I personally have the sensation something is missing. That is why I feel the crop is forced.
