Hey there!!
I think you art shows great potential and the more you create the better you'll get!!
I do think adding a bit of color would be a plus to your comic! In you banner the hairs and the "spiritual pets" have colors and it gives a nice touch to it! 
About the story itself, I like the raw idea!
The energy animals/creatures are a great idea!
The plot it's not making justice to the idea!
You start sharing a lot of information early on and it's too soon for the readers to get a bit more connected with the characters (or some of them).
I would say give us more context to their past/present or personalities for example!
I know you want to share with your readers everything because you are excited to share your story but you don't have to give all at the same time! You can keep more mystery to it!
Examples: Your character seeing things and other people around him don't see. Him trying to ignore an animal that is in his room and the pet is trying to get his attention!
All of those type of things would be fun to read and step by step you could introduce other characters with the same abilities
!
You can even give us flash backs if you prefer, since you already started, of past situations or context to previous events!
These are all suggestions to motivate you!
I think you have potential and the story too!
SO KEEP UP!
GOOD LUCK!
Hope to see more of your story!
