I struggled getting into my novel series until I went to first person and then the thing took a life of its own.
Just remember that it's restrictive in many ways and because of that I interspersed the narrative with other character third close POV's and that really worked well for what I was trying to do.
As others have said--if it is working for you then go for it.
However, keep in mind that close third can almost be converted from first person though there will be some immersive elements that might have to be removed to make it read well--or at least not read odd.
POV is really a big thing when you begin to analyze what it is that you are out to accomplish and sometimes the reader might not be so appreciative. There are really some very strange thoughts about why some people don't like first person POV. Some are well founded while others are repetition of what a reader read in some criticism somewhere and are just parroting. Well written first person often is not that noticeable and some people who say they don't like first person books have read them and enjoyed them, and just don't seem to remember them as first person POV books.
I also used present tense--which was a more controversial move and I've had some interesting discussions with a few people about that. While the largest problem with that is similar to the POV character dying, 'how can this person telling the story, be telling it right now as if it is all happening right this minute?' and for those readers it's a struggle of suspension of disbelief. However, it's more likely problems with the paradigm of secondary belief in that it is difficult to fit the narrator's narration into the the world view of the fiction. The readers that said they didn't like first person present tense, liked my novel, so I think that my choice that it fit the circumstances was on point.

Includes some great examples of the different POVs and when and where each one works best and also how it can change the tone of the story.
I was able to do some of these course series through my Comcast Xfinity plan for no cost--Otherwise it can be expensive. Though I think the audio version is available through amazon for around 30 US dollars.
