Good job, Vincent. Interesting use of pictures, but what's written in each of them is small compared to the space you left over in the pic. Either crop it or make the text bigger. Also, a link and video would be useful.

ReplyDeleteGood job! Next time add a video or link to enhance your post! I liked the pictures.

ReplyDeleteGood job on the post Vincent. Your post is very organized and have the information needed. For number 6 I think you should've added the prism to make it more explained to the people. Also a link and a video would help.

ReplyDeleteGreat job Vincent. I liked that you used colors well. I think you got the numbers wrong, like 6 is suppose to be 7 and 7 is suppose to be 9. Also add a video and a link to make your post better. Other than that, great job.
