This is not actually a problem for artists, but a problem for people who lack confidence.

I feel the energy from this 🥺

I have the exact same problem- I've daydreamed about comics I've wanted to make for YEARS, and every time I've tried.. Honestly, I usually don't even get past sketching a single page. My art has improved but I've never had the technical skill to bring my grander visions to life
Don't feel like you're alone, I've had plenty of artists friends who say similar things as well. But you're incredibly talented, and even if you don't have the skills to do what you wanna do yet, it's only a matter of time! Your art's incredible- from the composition, to the lineart, to the lighting and shading, everything about your artstyle really. I'll be happy to continue to support you as much as I'm able and look forward to seeing all the wonderful art you submit- and hopefully, I'll be able to see that comic you've got in your head one day ♥♥ All in time!
