In my opinion: One can critique the chef, without being a chef himself. You don't have to be skilled in said field for you opinions to be valid. Those who do critique that end up working in the same field normally have a change of heart. The hardships faced and self reflection gives allows them to truly appreciation and realize the amount of effort put into a piece of work.
A good example is Solar Sands who used to shit on low quality art before he himself started to create art. His content slowly changed from cringing and raging about shitty DeviantArtwork. To interesting and thought provoking art ideologies and works. LSMark and Daftpina also come to mind.
Dillin on the other hand. Has not let up his harsh critique. Which is infuriating to say the least. While his works are amateurish one would think to be lenient. But from what I've seen Dillin comes off as if he's knowledgeable and experienced. Hence the hate.
Also, I skimped through the first two chapters of "The Cyclone" and they are painful. Please send help.
