Nat Geo colour studies

I was cleaning up my old sketchbooks and found this page from 2023, it’s rough and experimental approach has grown on me. The drawings are using cuttings from old National Geographics as reference, and I had limited myself to only 2-3 colour palettes.

A sketchbook page with two images glued on it: one of two men, possible waiters or servers, in matching white suits and red bow-ties. The other is a school of small fish in a tank.
A sketchbook page with two watercolour paintings: one of the small fish, though stylized with extra big eyes. The other is of the two men in matching suits. Both use bright and bold washes of colour.
