Always remember to save all of your old sketches and doodles - fancy or not - as you may need them again one day! Who knows, maybe you'll compile a book one day about fashion illustration, maybe you'd like to have an ongoing portfolio, maybe you want to share with other fashion artists.
It's just a good idea to keep everything you've drawn, and if you don't have the space, scan your illustrations onto a computer and back them up. If you've only got illustrations on the computer (which is the case for me!) always, always back it up on another hard drive. It's awful to lose anything. Your drawings are an extension of your creative self!
Here are some old sketches I thought I'd share again with you! (You may remember them from before the website was altered)
