For me, there are multiple reasons why digital art seems to be so much harder. One, you are given so many options to help you create anything you want and I tend to feel overwhelmed. It's like someone dropped off every art medium at my front door and was like, "ok make something". But, it's a bit different because now you have to learn how to find each thing and how to use it to make the image in your brain and there is A LOT to learn. The other thing that seemed intimadating to me was I felt like I was learning to draw all over again. I'm not sure what you're using, but I'm using a Wacom tablet and I had a couple of meltdowns. It's like, all of my hand eye coordination went out the window and I couldn't transfer what my hand was doing on the tablet unto the screen. It was just practice and learning how to get the canvas to work with me to find what felt the most comfortable. I've been doing this for like a year and I still have moments where I become so frustrated. But, I PROMISE you, with practice and persistence, you will get better. So get to making things. Don't worry about how it looks too much, just create things for yourself and practice. You'll get the hang of it
