First of all thanks for your comment, seeing how my work inspired you to enter this world and bring your ideas to live really makes my day :-D
Talking about the experience in the field, I've been doing animation since I was very young, started with Photoshop and Flash and then moved to other platforms. My actual tool to create pixel art (and the one that resembles Flash the most) is Aseprite, wich allows to use layers, exports spritesheets, etc. Having a great tool like this enhances the creative process and saves you tons of hours (plus it's cheap!).
The good thing about pixel art is that it can adapt the complexity of an animation to the look and feel of your aesthetic and doesn't require complex visuals to look cool. Start with simpler graphics (like Superbrothers: Sword & Sworcery), test your skills and grow from there.
About creating an online course, right now we are ultra-focused in the development of our game so I don't have much time left for anything :-/
and besides, there are tons of pixel art tutorials out there!
I encourage you to check the ones from MiniBoss, they are very helpful and beautiful to look at:
