This week I challenge you to illustrate the concept ‘Invisible.’ This is difficult as everything illustration is the complete opposite. Try your best to use this description to stretch your imagination to it's furthest extent. I expect great things from you and I believe you can solve this challenge beautifully. As my last challenge was open for me, I’m going to do the same for you, any size or medium. That is all I have to say about this, as there isn’t much involved. I wish you the best of luck and like before I’m looking forward to the reveal in a week.
