thanks! I'm working to improve how I make the hair shine at the moment. There are a few methods I'm trying out on older sketches as I redo them.
yeah I used to avoid drawing certain things for ages, even now I tend to not draw hands and feet on my characters. I find that just doing an A4 gesture page or two of whatever is the problem will help to get over the feeling that you can't do something.
I totally get you on those problems!!!!!
the smoothness is something you do get used to eventually, although you can get more rougher nibs for your pens, or some people put a sheet of paper over their graphics tablet to get more friction. I do have different nibs but they all feel the same to me ¯\_(0_0)_/¯
If you zoom in more when doing final details, you will find that you have more control because your movements can be larger.
as for dealing with the canvas size (especially for final pieces), I took four years to get used to that because I was being an idiot. Thanks to my increased efforts lately I finally got the hang of it like 2 weeks ago. Basically I have almost always sketched at the same zoom for my random pages like this one
So you start to get used to what you can fit. Once I start an individual sketch, I very rarely move out of that screen so I know what what I am drawing will fit. I often glance around to see how much space I have underneath or to the side so I can sort of plan my next sketch as well. for a final piece style sketch, I do a really loose sketch like the ones in my step my step, as large as I can, often while I can see both the top and bottom of my canvas. I then either rescale the layer immediately, or do an over sketch or two and rescale all layers to the correct size to suit the canvas.
I used to do this a lot, where I finished the sketch as it was on the page
but that means you don't know what your final image size is, and choosing brush sizes will not be as natural etc. And if it turns out really good, the resolution is lower than your normal stuff. So I really recommend if you "happen to do a sketch that you want to finish", copy it to a new page of the same dimensions that you always work in, and rescale it to fit. I use either A3 or A4 @300dpi so I always know what to expect when I draw. Or if you start out to do a finished drawing, work at really low zoom to start off with the balance everything out but no details, then zoom in and you follow your previously laid guidelines. Then you know everything will fit.
hope that gives you a bit of a direction to go in.
