No one can retrieve your data, photos, etc from your iCloud account on the old phone without your Apple ID. Did you turn off "Find My iPhone" before wiping it? Your photos may still be in your iCloud back up, unless you have backed up your new phone. In that case they should be gone. You can check iCloud and see if the old back up is still there. But as far as someone seeing anything now, it's not likely without your iCloud log in. If you think someone knows your Apple ID, you can reset the password here.
