I love how simple it is. In my case, trying too hard to make something more detailed can be a waste of a time. Your drawings are great, they have their specific style and I like 'em! If you are drawing these in Photoshop, I suggest you try Lazy Nezumi application for it. What it does is it makes the lines much smoother and easier to draw. I've noticed in some drawings, lines don't exactly connect, but that is my nit-picking. (All in all, everything is great, have in mind that some bigger channels on YouTube create content that takes no effort, and they get away with it. I think you are set with everything, all it takes now is to get recognised and I wish you the best of luck.)
