When Ymir recieved her shifting powers her shifter form looked almost exactly the same as her pure form. Eren on the other hand shows a great difference between his pure and shifter form.

What's the difference between the two?

Ymir spent 60 years as a pure titan while Eren was pure for less than a minute.

This becomes even more plausible when it is shown that Zeke imagines that Armin's colossal form is (possibly) just as high as bertholdt's one, And you guessed it; Armin was a pure titan for only a very short time.

What do you think about this?
