There you are quite right. 1st person and 3rd person makes a big difference, Just as the vessel or the written MC. But those Vessels dont really work out. You need to indentify with the words the MC says and a lack of those creates a feeling of passivity, which feels like a personality trait as well. I am not a fan of that approach as well.
Your third person perspective took a moment of adjustment for me as well, but you designed him very good. So the adjustment worked well. But i wonder if it feels different for you as well in the writing process. Like if there is less inclination to articulate equally pronounced feeling as in 1st Person. I could imagine that there are subtle differences. For writing you take a position in a narrative inverionment as well and a different perspective might change something there as well.
Well thx for taking your time to answer my posts. Much appreciated. Have a good time making your Artwork.
