Last weekend I tried my hand at portraits despite having zero training on this. Just picked up a newspaper, opened a random page, and attempted a few mugshots from it.
Managed to get some degree of likeness with the actual pictures but eyes do seem to be a tough area. It is not for nothing that they say that eyes define a person's face. You get them right, and almost everything else will fall in place.
As my dear hubby rightly says, portraiture is all about lines. You have to know which ones to use and which ones to skip.
With one of my favourite Bollywood icons, the inimitable Dev Anand passing on last weekend, I just have to try sketching him now.
