Yes, i grew up watching Bob Ross and have always loved him. If you haven't seen it yet check out his biography documentary! I photoshopped (ms paint) my face into his afro for my profile pic here! hahaha

I would bet developing is a world of difference to writing and creating content for a blog. However, the art communities and the opportunity to engage with your art are pretty incredible. Having your tech background should make the learning curve a lot easier to manage as well. If this first post is a launching point for your 'blog' then i think you are going to do just fine on the blockchain! It takes a lot of people much longer to offer up a post of this quality level.

My main tip would be to have fun. Express yourself and the more you share of yourself, your art, and the process the more well-received you will be imho. It does take a while to get traction but a big mistake some folks make that create great art is to just post the art with not much info surrounding the content or process. In those cases, less isn't more. A little effort goes a long way. I can tell you put effort into what you do... so just keep up the great work and i think you are really going to like it here! Take care bro!
