Then watch something else. I don't know where you got the idea that Hilda was the be all end all for examples on the this emotional feeling you want to replicate. You need to take it upon yourself to figure what about Hilda made you feel this way. You don't think it's envy, you say the emotions aren't negative and that you think Hilda could be used as a source of inspiration. Well it doesn't have to be the only source. It's time for some introspection on what content brings out this feeling in you. What attracts you media-wise and why is that the case. Do they remind you of a good memories, was a scene just really cool? Once you figure that out, it'll be easier to replicate that feeling but with putting your own spin on it.
I feel like you mentioned before in a previous topic how you want to get to the cool scenes but not was to worry about all the build up to theose scenes. I don't know if you decided to write around those scenes to give them more impact, but without that mindset, your scenes are going to come off shallow no matter how much effort you put into them.
Maybe take a break from content creation and go consume media you enjoy or are similar to the video you're going for. Watch tutorials on youtube about character creation and storytelling, listen to other creators talk about their struggles in regard to making things they like, and practice drawing. Practice, meaning you don't have to show it to anyone. Then, after all that time of soul searching, learning, and practice, watch Hilda again. By then, you should have the tools to understand why the show made you feel the way you felt. And instead of being a point of contention, it can be a point of inspiration alone.
That's my advice, though you are free to ignore it and figure out something for yourself.
Lastly, ineptitude can be fixed with time and work. Ambition will grow when you goals become more clear. And I understand you feelings of being inauthentic with you art; my work has been called shallow before, and while it stung, they were right to an extent. It can be hard to put yourself out there through the work you make, but authenticity isn't based on how emotionally raw or deep your work is. There are plenty of people making authentic things that don't pull at the heart strings. Authenticity is based on how honest you are when it comes to your work. I'm being authentic when it comes to my art because I enjoy making it and looking back on it, or it speaks to the kid in me. Maybe you're not at that point yet but I'm sure you will be.
