Man not to burst your bubble, but you are carrying a decent amount of bodyfat at this point and you still arent big enough to go in at 180 shredded especially running natural.
I respect the goal, but since you competed last at 155, why not shoot for a realistic improvement of 165, even that is alot of lean tissue gain for a natty to come in at his next show.
I know, I compete too, Im not badmouthing ya, I just know what happens to us naturals when we get to fat in the offseason and try to move up a class. Its hard as shit to strip that fat and maintain lean tissue if cardio is necessary.
I have some pics in my gallery. Im your height and compete bantamweight at 143, I have a small bone structure and can carry a decent amount of mass at that weight.
Good luck on your goal, but I think a 25 lbs increase in competition weight just aint gonna happen naturally in less than a year. good luck with your preparations,
