I'd not look inside at that stage of the flare. It will most likely cause you issues in the future. On a windy/gusty day you will have your hands full controlling the aircraft, the last thing you will want to do is look inside!
As others have said don't worry, it will come with practice. You will learn the 'correct' view out the window quickly and so whilst flaring will be able to just feel/see if you are high/low or have caught a gust/sink
