potrait illustrations

is it neccessary to have graphic tablet while doing potrait illustrations? thnx

it depends, it isnt completly necessary have a graphic tablet if you want to draw in digital, but it is more usefull than do it with your mouse

Not necessarily, but it sure helps!

Depends on what you want to do. If you want to make digital paintings you should use a tablet. If you want to do simple vector graphics you don't necessarily need a tablet. But it does help you either way, it's much easier and more intuitive than using a mouse or trackpad.
