Not every brand needs exclusive illustrations, but when needed, nothing can replace them.
If the illustration is a core identifier of the brand, invest in a unique image as it is an exclusive asset that cannot be confused with others. If the illustration only serves as an accent, using an existing library is still fine, as long as you choose from the same set, with a consistent style, and carefully check the commercial license. The biggest mistake is not choosing a library but rather mixing and matching from various sources, making the identity look patchy.
This question is actually about the role: where does illustration stand in your brand experience? Answering that question will resolve the budget question.
This is the first and most important determining factor. Illustration plays a core role when it appears frequently; it is what customers look at and immediately recognize the brand, such as product packaging, mascots, children's brands, or brands that tell stories through illustrations. In these cases, custom illustrations are essential as they are identity assets, not just decoration.
Illustration plays a decorative role when it appears sporadically to soften the page, enhance the liveliness of social media posts, or illustrate a specific article. In this role, available libraries can do the job if you choose correctly.
Choose a separate illustration when meeting at least one of the following conditions:
Individual illustration is a long-term asset. The initial cost is higher, but you own it completely, and no one else can use that exact image.
An available library is a reasonable choice when illustration plays a supporting role, the initial budget is limited, or the brand does not have enough opportunities to use images regularly to justify the cost of creating custom designs. However, using the library correctly requires discipline:
Sinh Vũ does not hold a rigid view that custom illustrations are always better, as this entirely depends on the true role of visuals in each specific brand. For brands that require a unique quality, custom illustrations are included in Sinh Vũ's premium package as part of the brand identity system. For more compact packages, Sinh Vũ provides specific selection principles to ensure that the visual library maintains a cohesive quality and does not appear patchy.
The brand archetype directs illustrations. Exclusive drawings that serve the brand character create differentiation that a common library cannot provide.

The question you should ask yourself is not "Is the illustration expensive?" but rather "If we don't have this illustration, will the brand lose something distinctive?" If the answer is no, a curated library is sufficient. If the answer is yes, then it is worth investing.

No, if you choose the right method. The issue is not the source of the image but consistency. An identity system that uses a library but selects the same style and set of images will look much more polished than separate illustrations that use different styles each time.
You need to carefully read the terms of each library platform, especially distinguishing between personal and commercial licenses, and check if exclusivity is granted. Sinh Vũ often guides clients to check this step before including images in the official identity system.
It is completely acceptable, and this is often the most reasonable choice. Create unique illustrations for key positions like packaging, homepage, and core documents, then use a library for the rest, but it must be customized to match the quality of those unique images.
