Well, first off, I have to say that the character interaction is awesome. I could see this as an animated film done in a bit more of a realistic style.

The plot definitely could have potential. However, you have a lot of room for improvement as a writer with time and practice.
You can use description and do have wonderful details to support it. However, you need to concentrate and show through this description tying it to interaction, action, and the sensory. You have some wonderful characters here that do have some depth and despite they interact wonderfully through dialogue such is an excellent place for some linking description and to help reinforce character iconography so there faces can be recognized for the audience. This needs to go beyond the cliché elemental/”god”/scale/color tropes you present for your audience. Despite a pure archetype is very understandable to an audience it often creates holes in the logos that need to be explored effectively and does not a character always make.
Despite fiction is fiction and fantasy is fantasy we have some biological problems that need to be addressed in the raising of this human child.
A beginning is an important thing as it is used to addresses the audiences attentions. Reflecting on that, the beginning could be made stronger by reinforcing these listed (Do not plainly list within fiction) emotions to a narrative element.
So you have ideas and a base, time to take it to the next level which I believe with time and practice you are very capable of.
Best of luck with the rest.
