stay away from the cliches. don’t have two characters kiss within the first chapter, build the relationship throughout the story. give them chemistry. Detail. Details are very important in order to draw the readers in. Always check your grammar and spelling, and also stay in present or past tense. Do not switch between the two, it’ll confuse the reader (i struggle with it at times). I prefer to write in the 3rd person because i personally feel it helps be more descriptive, but 1st person is alright too. Hope this helps a little. Thank you for your kind words
