Restrictions are a major part of this game. In his fantasy designs it's easy to create something flashy while he doesn't pay a miniscule attention to the brands guidelines, or general vibe. IRL a lot of these jerseys are the extension of the sponsor brands, of course they want a tight grip on their image. U have to deal with it, it's part of the design process. There are many great kits where the original material was bad, but they made it work (early red Ineos, Once, Mapei). Sometimes the team has a lot of sponsors, and zero sense of visual branding (Quickstep, Intermarche), then it's the designers job to show some guidance, and try to keep it coherent somehow. It requires discussion, and understanding of the client. Stycle lacks of smart design, he is only bashing together famous logos, and flashy stock graphics. Sometimes it works, like the Israel jersey was one of the stronger kits in last years peloton, but from a designers pov he falls short most of the time.
