ThankYou . . . . . so much for the appreciation, well . . . . . I start designing and finish it with a background, and the important thing about a fashion illustration is that it should not be flat it should have some story behind it . . . . . or your inspiration as a background. And NO . . . . . I had never learnt illustration actually no special classes, I was a fashion student . . . . . but YES I had started sketching my ideas very early. Learn from your own sketches and try to improve them, prefer fashion magazines for poses, silhouettes, folds, fabric rendering etc. And one thing never imitate anyone, if you are not good at anything never do it (like I'm not good at facial features eyes&nose so I never draw it). Try to personalize your illustration . . . . . GOOD LUCK !!
