Comment on Tutorial - Nailing Lineart by TwilightSaint
Glad it could help. ^^ And there's really not any secret to how I do it, I just have a really steady hand and lots of hard work under my belt. And detail is king - textures, wrinkles and folds in skin and fur, it just adds a million miles to any piece.
And I'm guessing knowing how and where to use those kinds of details is just one of those practice things, huh? XD Guess you can't cover everything in a tutorial. That makes more sense, though, thanks for explaining that. It's neat that you get lineart like you do without doing anything special besides just drawing it. 
Yeah. XD Honestly, it's tons of hard work, as well as lots of experimentation and just learning what to do, and how to do it. I know for me, once I get something down, I got it - it's like riding a bike. And then after that it's refine-refine-refine and refine some more, and then try something else!
