It really depends on what the reader likes. Change, for some, is good. The third person can be quite boring if you don't add the right amount of details, whereas the first person allows the reader to step into the character's shoes. Though I do find writing in the third person to be easier (for me, atleast). Change for you could be good, where you've used the first person thus far. So I do suggest changing up the POV and see how your readers react to it, if they like it, keep it and if they don't, switch back to the first person. Sometimes if an author uses one POV for so long they tend to become boring and predictable, or rather the character does-the readers, understanding how a character thinks and acts, will automatically know what the character will say or do, thus making the story predictable.-So change is good, I say go for it.
