Just a nice clean design with a lot of potential information! Although I feel they're a bit large. For me personally it would have been perfect if it was half the height. And yes, I feel like more filament swatches should be orientated vertically. Most of them are designed with all kind of transparency tests etc. and are unusable/impossible to be printed vertically. The top layer is the most ugliest layer of all, normally speaking. So I also think you might want to have designs that can be printed upwards, to get the best color(s) impression. Keep up the good work!
