>>4462303How long have you been drawing digitally? Your clean drawing has that look that mine had when I was new to digital. When the stabilizer was maxed out and I was trying to draw every line in one clean stroke because of the awkwardness of tablet drawing. Two things will help with this.
1. Just plain get better, more knowledgeable on all things drawing. I'm not insulting you, we can all get better and I don't know what your finished/best work looks like. But knowing how to draw better will translate into any medium and you'll draw more confidently, meaning more confident lines.
2. Turn down the stabilizer and practice lots of digital drawing. You don't have to turn it off completely, but lower it as low as you can tolerate and accept some wobble in your lines. It'll add character. Learn to build up line weight by drawing in areas of emphasis multiple times. Don't trace your sketch, instead reinterpret it and make it better. Drawing is iteration.
