The basics about marker drawing with Copic (#nospon)

Now that the ‘sort of short update’ is out, you might understand that I couldn’t stop learning again. I have been really into illustration lately, nature illustration to be specific, and I joined Patreon classes, red old school books, finished Youtube completely on this topic and went to art-supply-stores, which is NOT good for your money. Meanwhile I was soaking the knowledge like never before. I am a sponge, because it makes me só happy again!

And why not sharing all this? I thought that would be a nice idea. 
I hope someone is going to be as happy as I am with all the information below :).
