This is a great idea--especially because most seed and plant retailers want you to buy 25 of each variety of berries that you'd like to try. That's fine if you have acres to plant them in. There isn't room for hundreds of berry plants on my roofdeck.
On the other hand, I think you should say which varieties of berries these are, and whether they're single-crop or everbearing.
The strawberries all died but, The raspberry and blueberries are doing wonderful.
