Why is malphite so small in his Ironside malphite. (Also semi calm rant about size of Malphite)

I love this new skin (instabuy) but why is he so small in his splash art. Even while crouching he's a midget compared to most of other Malphite's representations. As you can see he is huge one man is the size of his fist just his fizz and then Ironside Malphite is only like 12 feet tall so the size of Aatrox and a half of another Aatrox and then original Malphite is like top of my head is fist is like 1/5 of his body size a man that is about like 6 feet so a foot smaller than Aatrox so original Malphite is about 30 feet tall we have an 18 foot difference so why is this new Malphite so small? Like I said I love this new skin I love the new sfx,animation, and recall my only real problem is why is this Malphite so much smaller than the their Malphite's. Or the better question is why is there such a difference in sizes in all of Malphite splash arts. His Frozen and Ironside Malphite is is smaller than original, marble Malphite is about the same size as original, And finally mecha and obsidian Malphite are a lot larger than original Malphite. Why is he morphing sizes so much compared to any other champ. Could we get any explanation and the case of malphite right now since he is shrunk down in the game for ovbious reasons but now a man Son is larger than him of course it was technical limitation but its just getting confusing at this point.
