I wrote a story where people live on a new planet and they each have a magical power.
What type of magical powers do they have in your story?
Everyone has a different one, come people are invincible, some control elements.
Does your planet in the story have gravity like so many others in our Solar System?
My planet is a lot like earth, although I haven't really thought about the gravity aspect. I always thought it would be cool if we could float a bit like when on the moon.
That would be cool. How long are the stories you write? Short stories to grab quick attention of the reader or long stories where the reader is more invested? 
Long stories usually. The one about powers is a Trilogy but will have a few more stories added. The people and planet are interesting enough, in my opinion.
Do you have a protagonist in your story? What are their main characteristics?
The main charcter is sweet and very caring. He is a great friend, son, husband but when his wife is murdered he gets bent on revenge to the point it may kill him.
Oh wow. That seems like it would catch anyone's interest. Revenge seems to be in all the good stories over history.
