Those are beautiful sketches! Those are some confident lines you have.
A lot of people when they hear that you are an artist, they think you can do EVERYTHING. I had to explain to them why I, as a fine artist, can't do character design simply because it's not my field. They be like "but you can draw". They think it's so easy to do all these stuff and even though they are kinda related, they aren't exactly the same lol. It takes a lot of years of training to do them and do them effectively. It's not as simple as drawing a cartoon animal.
Thank you.
You're right, and I think it's pretty much the same in every field; when people don't know a discipline at all, they minimise it, it's a kind of ultra-crepidarianism. It would be like asking a maths teacher to teach languagues just because he's a teacher, after all, lol.
