  1. Great Job Danicka! Your pictures were very well detailed and easy to understand. Also your link was also very helpful I think it helped a lot of people. But 2 suggestions I have is that you could've added some color to make it eye catching and a video to help others a little more but otherwise great job and keep up the hard work!

  2. Nice job Danicka, I really liked your pictures because it explained what question you were doing. I agree with Alyshia that you should have added a bit more color so it can stand out more, but other than that great job.
