I have some criticisms, but please don't take it personally or let it affect your future project.
-Art style was stellar and was giving me some Bush Hartman vibes. Though the red nosed old man clashed a little bit for me style wise.
-Animation was pretty good, though could be better. Some parts were a little stiff, but if you've been working on this for 2 years, it's only going to get better from here. Just work on conveying motion as well as you can.
-The Plot was probably my biggest gripe. It was a bit slow and uninvolved, a lot more pause than necessary and the older guy's reluctance to say anything was repeated a lot and very empty. He felt pretty empty as a character despite having a pretty good look. I think you could have conveyed the scene better in less dialog by only saying it once with the 'Our family has a lot of secrets that we can't tell you'. He said she was the only one he could rely on, but that was never really made clear or anything, so it just ended up dragging the scenes on. She wasn't revealed to have any special powers, or being the only one able to use the scythe etc.
I think in future episodes you should really try to plan out a really good flowing scene. Might even save you some animation time in the long run. Make sure the viewer is never bored.
Hopefully this helps and doesn't just come off as being a jerk for no reason. I just want you to make your best work going forward. Good luck!
