While it's big enough, I wouldn't use it. You will want a backpack! Trust me on this. A bag like that will get extremely heavy and could damage your shoulder
I would suggest getting a backpack to save your one shoulder from carrying so much weight. I usually carry a lot of books in my bag and I don't think I could ever going to a bag I hold on my shoulder because I would have shoulder problems, I know that for a fact.
well yes it is really pretty and it might hold all your stuff but I don't know how big it is
its ok but i would go for a slightly bigger one width wise
