I really like your page; its clean and simple without being boring, and the brown background to your main picture echoes the brown of the mushroom gills nicely.
Your text is well-written, which I think is often neglected when designing webpages - a good balance of humour and seriousness.
You’ve packed a lot of information into a small space, without it being too dense.
My only real suggestions would be that:
i) I think you need white-space between your sections in the same way that you had a gap between your picture and main text.
ii) I think it would help for your lists to start from 1 in each benefits section instead of counting from 1 to 21 across them all (benefits to the skin 1, 2,3 … how mushrooms benefit the the hair 1, 2,3 etc)
iii) Maybe have your “life saver” text as a subtext under “Tribute to mushrooms”
iv) I think we need to avoid using bootstrap for the beta curriculum - see campers post further up the thread
Other than that, good job!
