By the time you've drawn as many MegaMek sprites as I have, you realise that Scale in TRO Artwork is an abstract concept at best and a joke at worst. The artwork is rarely, if ever, drawn with anything to give it a sense of scale beyond "the cockpit goes here" and making assumptions after that. There are massively oversized Light 'Mechs (eg Puma), overly fat Heavies (eg Linebacker), small Heavies (eg Kuma), 'Mechs with no scale refences at all (eg Stalker) and so on.
By being consistent, these redesigns are making a world of difference
