The visuals in Tak are wonderful. The FMV cut-scenes alone rival just about anything else out there for the PS2, except maybe for the Final Fantasy series. Of course the quality of the FMVs only means so much. The quality of the rendered graphics is far more important. The simplest way to describe the graphical quality of Tak would be to say that it's on the same level as, let's say, Jak II but without the same level of polish. The animation is seldom jerky and feels just as fluid and smooth as any other platformer out there. The only big problem with the graphics is a lack of diversity. While many of the areas have a diverse look and feel, such as the snow/sand boarding areas and 'chicken island', the jungle motif is present in too many areas and can cause the game to become a little tiresome prematurely.
The jungle isn't exactly a quiet place and neither are the areas in Tak and the Power of Juju. Between magic spells, monkeys and giant orangutans, there's plenty of variety in the sound effects. The music is pretty much typical platforming fare, except with more emphasis on rhythm and beat, likely because of the jungle theme. Another thing definitely worth mentioning is the voice acting, which is top notch.
