As an origami hobbyist for over a decade, I feel that this set only uses Origami as a veneer and isn't truly related to Origami.
I have a large collection of origami books (60+) from around the world that detail many kinds of models and designs as well as the theory, mathematics, and history of Origami and so I feel adequately knowledgeable to talk about Origami and how it's poorly represented here.
Firstly, the banner graphic for this set shows 2 models, an airplane and some bird. Traditionally, paper airplanes don't really count as Origami, mostly because they often start with non-square paper and often include the use of glue, tape, or multiple pieces. In general though, paper planes don't fit the main intent of Origami, which is the re-creation of nature in paper. The bird one, while being nature derived, looks like someone who doesn't fold/design origami made it digitally. The lines themselves don't make sense in terms how Origami bases are folded. The body has just so many triangles that really wouldn't appear like that normally. On top of that, the wing is also something that wouldn't normally happen. For the bottom part of the wing to end in the middle while the top part extends out would mean an intentional design around that wing vs a natural base design. It's also incredibly 2-dimensional. This is obviously incredibly nit-picky of me, but as someone who's been an Origami Hobbyist for a long time it makes me feel as if the design behind this is was very superficial without much understanding of Origami.
As for the colors, the grays in the base kit don't really make much sense with the theme of Origami, gray and dark gray aren't really "iconic" or "related" in my opinion. The blue is even further from the theme, in my experience, blues used in Origami are a much more royal blue with deepness instead of this teal.
Lastly, while most of the icons look very good and accurate to traditional origami, the choices of models seems a bit odd. The airplane on the Enter Key doesn't feel right to me, it's a pretty prominent key to put something that's not really traditional Origami. The lines on the other models are much realistic and show depth and shape that's very relevant. I think the choices of which models is a bit odd. I'm surprised to not see a traditional crane. They're very simple but incredibly iconic of Origami. The first novelty definitely fits the theme, is iconic, but I wouldn't choose that bird over the crane. While the Fish, Whale, and Dog are all accurate to me, I feel there are better models that could be shown. For example, I'd recommend the turtle, frog, rabbit, boat/hat, or some other ones. They're still cool though. The elephant, if you chose that specifically because of Alain Georgeot's elephant exhibit in which 88 different elephants were made from artists around the world, then I'm deeply impressed. I have a feeling though the choices for novelties were more of "this looks cool".
I like the look of the set in general, although it is very close to Modern Dolch, but I would definitely not agree that Origami is represented well here. This is your set and you're obviously free to design as you'd like, but I feel I should express that this really isn't an Origami set.
