I'm sorry if i came off as show-offy or rude, or even arrogant. it's just for better understanding as your tutorial is very popular and one of the first results when you search for wing tutorials.

Thank you so much for this brief explanation about the anatomy of wings! I would let you see my outcome in my recent piece [link] (if you think I'm spamming just to recieve some visits feel free to hide my comment)
