IMHO: Technically, very clever but too much going on. Maybe better to be more selective of what is in the image. Also, not very attractive or spirit-uplifting (that is, ugly shapes not conducive to long-term gazing).

The above were my initial impressions but, the more I look at the image, the more I see in it and the more I like it. Maybe it is an image that grows on you? The "holes" in the far wall are intriguing and probably worth a shot by themselves but such a shot might look too obvious. I would like to see a version of the present shot with the light areas outside the cave (in the right half of the image) toned down so they are as dark as, or darker than, the interior tones and are not distracting, and attention is kept within the cave.
You also need to lighten the horizontal "bar" in the centre of the image and the interior of the wall at the right end and lighten more the left end of the bar to direct attention to the holes in the back wall. Then, you need to lighten the far wall and bring out detail in the dark holes.
Finally, you need to darken the light areas around the edge of the shot so attention is drawn into the picture.
You can see why I seldom get any of my photos finished!!!
Roger, again
