The first word that comes to mind to describe this is: Impressive. This should be a mural in a public place devoted to art or learning, say a science museum or public library.
OK - now for the details. The second word that comes to mind here is: Expansive (in the generic sense, not as used in enneagram). This is what suggests the scale of the collage. It comes from the broad bands of color on the top and bottom, the sparseness of some of the images (upper right with single bird against a red background) and the prominent use of RED overall. Overall the collage acts almost as a colorblock or quilt-like image, except that the blocks are not solid colors or abstract patterns, but actual images with distinct and appealing content.
The images seem very carefully curated, both in content and sizing and placement. There are common themes: birds, flames, the sun; also solitude/independence, focus on nature and open spaces. The bottom strip of purple flowers at first seems out of place, featuring a color found nowhere else in the collage, but somehow it works. It says to me "I put this here because I can." Overall, this collage combines the grand and the ordinary; the vast and the focused. I think it is this contrast that initially gave me the sense that it doesn't hang together, but the more I looked at it, the more I saw how it did.
So, what does all this mean? The expansiveness based on color, sparseness, and openness of the layout suggest someone who is comfortable putting himself out there, or at least comfortable being seen and given attention. It is not attention-seeking, but rather attention-accepting, perhaps even attention-appreciating, especially if that attention can be put to good use. A key part of that is the ability to control carefully what people see when they do pay attention.
The nature of the images suggests someone who, despite the above, really does enjoy having personal space, peace and quiet. They suggest a love of nature, or more accurately, an affinity for the spaces, sights, and sounds of the natural world, especially those evoking free-spiritedness, tranquility, and beauty. The purple flower image lends a dash of unpredictability, a sense of doing the unconventional, just because, and knowing it will turn out OK.
The combination suggests a person comfortable in the public sphere, almost in the manner of a noble, graciously sharing his presence and gifts with others, but on his own terms. Look carefully beneath the surface, listen behind the careful speech, and you will find a gentle, introspective and independent soul who appreciates beauty in its most elemental form, and would willingly lose himself there, at least for a time.
