Hey. If you want to add something to your description, Yutyrannus is part of the Tyrannosaur family, has a good sense of smell, and has feathers of the same color of a snow leopard. It would have Keen Smell and it's Bite would have Grapple like the T-Rex statblock and it can also Pounce and Surprise Attack. And It would have Darkvision because it can also hunt at night. Darkvision is 10+Wisdom Modifier.
Long time no chat. You forgot to add Keen Smell and Pounce to your Yutyrannus statblock.
