Does this sound good for weight loss, female teen?

For breakfast I had a serving size of whole grain cereal with skim milk. For a snack I had a cup of fresh blueberries. After that I had a slice of whole wheat bread toasted with light margarine. I went on 1.5 hr hike then had a protein shake with skim milk and a banana. For Dinner I'm having a chicken burrito on a whole grain tortilla with lettuce, tomatoes, onions, chicken, black beans and a little cheese. Does that sound good if I'm trying to lose weight? Thanks(: oh and I'm doing yoga for an hour tonight.
