Many people who come to the forum are very interested in the photo mosaic work created by Studio Artist artist Charis Tsevis, which is generated using Studio Artist's movie brush painting features.

There are various factory photo mosaic and movie brush presets that ship with Studio Artist, and others available for download via some of the links i mention below. You can easily modify these to use your own custom movie brushes with your own custom images inside of them.

Photo mosaic effects and how to duplicate Charis's work has been extensively discussed here on the users forum over the years. So you should do some searching through the archived posts here. Here's one old post to take a look at that discusses this topic.
Here's a post that very specificly describes an approach you can use to create sub-nested tiling photo mosiacs, which is somethign that Charis does using Studio Artist quite a bit. Sub-nesting is a term used to describe the adaptive sub division of the individual mosaic tiles going on inside of what people would consider a typical Tsevis style photo mosaic. So detailed areas of the photo mosaic image are sub-divided with smaller tiles to generate more detail in the photo mosaic image representation of a larger main image reproduces by a tiled mosaic of smaller secondary images. Sub-nesting means that any sub-divided tile is complete dived up into smaller tiles.
Check out the post link above to see an example of this and an explanation of one way to create it automatically using Studio Artist. Like most effects you can generate in Studio Artist, there is typically more than one way to create it. This includes photo mosaics, photo collages, and sub-nested tiling.
You can of course re-create Charis's signature styling effects. But we would encourage you to explore Studio Artist's extensive feature set to customize and create your own unique personal artistic stylings as well.
