Everything needs a re-check at the end. Having said that, with drawing you can't do everything correctly at the first place, it takes a lot of checking and re-checking. So, never draw darker lines and darker shaded areas, at the first place.
At the beginning, draw rough patches and images, once you are final about it, keep them darker. Don’t overdo the work.
As a beginner, aspiring to get the first portrait correct and neat is most precious. But, how should you go about? Worried? No worries, here we give you few tips to follow and take a note of, so that your first portrait, be it whatever, will be good in all angles! Take a look:
Holding the pencil is very important in thedrawing. When to hold at the nib, or at an angle, or holding the pencil loose or too tight decides how your image looks like.
To cover larger areas, hold the pencil perpendicular to the line. For softer lines, with details, hold the pencil parallel to the line. Hold at the point only when you work on intricate details.
To make your objects look clear, separate from one another, paying a hint to the line weight really helps. It helps in emphasising the shadows or shadow effect. To convey a 3D form, you can create thicker lines, which looks like disappeared in the shadows. Outlines totally black out your 3D effect, so to retain the effect, keep your outlining work to Nil!
