This review is written in May 2022, when 82 images have been released. I purchased this product when it was $40.
There are several main types of art featured so far, and each has their own style, so consider the following as separate reviews.
Line Art (7 images): The line art features a number of characters, scenes, and landscapes. The lines are clean, and a few images feature action that is exciting. I would rate the line art 5 stars.
Color Illustrations (Roughly 17 images): The color illustrations feature creatures, items, and characters. The styles range from flat line art with color, digital art, and some art that appears to be traditional media. This art is largely quite good, with the traditional media looking a little out of place compared to the other pieces. The creature art is the best in my opinion. I would rate the color illustrations 4 stars.
Photobashed Images (Roughly 58 images): These images look like thy have been bashed together in an image editing software, and then either put through a filter, or painted over digitally. They largely feature fantasy characters, landscapes, and magical items. These images vary in quality, with some like the Assassin Elf and Old Wizard looking great, while some others have evident crops. There are some characters where the body looks illustrated, while the head looks like a photograph. Many of the magic items look out of focus, or fuzzy. Overall, with the varying quality in these images, I would rate the Photobashed Images 3 stars, with the knowledge that some individual images are 5 stars, and some are 1 star.
Ultimately, it's up to you to make sure that this art fits your style. Make sure to download the full-size preview so that you can actually get a good look at what you are looking at, as the smaller view may not reveal many details.
