Good to see you finally get it completed.
I have watch it again and here is another few thing you could improve.
1) Creep selection - I am glad you take my suggestion, but I have to said you make a wrong selection for the creep inside the forest. Dog is definitely not a good selection.
From what I seen, it seems like you use dog more than any other critter. The best critter for forest scenery would be stag, rabbits or boar.
It also not complete without a flock of bird. Try use destructible/doodad of bird to enchances the view. If you ever goes to such a forest, tell me which forest does not have bird.
I only seen 1 critter per scene, the most is 2. It was recommend at 3 per scene and try to trigger the creep movement instead of allowing it to wondering cause if you allow it to wander randomly, it won't be same everytime I watch the cinematic and there is a possibility of it to run out of the camera sight.
For example, you can set a stag at the path of the guy walking and make the stag run away upon seeing it to make it more realistic.
2) Sound Effect - Good to see you add sound effect, but it seems like there is no sound effect of raining at the graveyard scene (I could be wrong, but you can try to take a look).
3) Tomb - From what I seen at the image, the tomb doesn't look normal. It just look like a rock that does not engrave the name and the birth/death of the person.
If you change it with a tomb that engrave with name and date of birth/death. It would be even more realistic and cool.
The 1st and 3rd reason I mention is more like a bonus and visual enchances, you can choose to do it or not to do it. If you really enchances this, I really have no reason not to give it 5/5 (Highly Recommend).
My rating at this moment is 4/5 (Recommend), it was a very high quality work that follow all rules guidelines, excellent coding with all basic cinematic setup on it, high detail terrain and follow the exact theme of "Sorrow".
For those who want to watch high quality cinematic, this is definitely a good choice for you.
