TADNE is trained on n ~2.8m source images (augmented to ~4m), covering k ~ tens of thousands of different characters. OP is trained on... I'm not sure because the site is devoid of any information, but I would guess it's closer to 10k images from a few hundred characters at most. So the diversity will be drastically reduced, although the use of -ADA should mean that it doesn't overfit as catastrophically as one would expect from previous GANs to such small n/k.
