I both agree and disagree with you lol Yes, there are a lot of free watercolor guides/tutorials and resources online but the decision to charge for a tutorial is completely up to the artist. Just like some photographers choose to let their photos be freely used as stock images while others charge for the same or similar image.
I have free guides on my site all the time but that's again up to personal preference
Well, I really didn't think my style would appeal to everyone when I put this out there. There are a number of people who are interested in learning how to paint in my style and this data point has garnered sales on my behalf, but you're not one of them and I can't blame you for that.
I took the time to look at your gallery and found your portrait of Loki quite good, the draftsmanship was at a pretty advanced level. I believe you have a talent in portraits and should work more to cultivate it.
