What do you bro's think of this shake while bulking?

heya, its pretty generic but id like some input as to how to improve it in the aid of bulking(minimul fat). at the moment i throw in the following:

1 large banana
whey protien powder
2 cups low fat milk
approx 40grams oatmeal
desert spoon of honey (post workout)

at the moment i have it three tiems a day. once after workout(with honey), one before dinner and one before bed.
any suggestions to do with nutrition, not flavour, would be greatly appreciated.

cheers all and merry x-mas(im in aus so its xmas eve).
