I will begin with what in my opinion is your lack of restraint. You are like a spectator in a theatre who expresses his enthusiasm so unrestrainedly that he prevents himself and others from hearing. That lack of restraint is particularly noticeable in the descriptions of nature with which you interrupt dialogues; when one reads them, these descriptions, one wishes they were more compact, shorter, say two or three lines.

Anton ChekhovIn displaying the psychology of your characters, minute particulars are essential. God save us from vague generalizations! Be sure not to discuss your hero's state of mind. Make it clear from his actions. Nor is it necessary to portray many main characters. Let two people be the center of gravity in your story: he and she.
