No problem. You can follow the link in the post: https://steemit.com/contest/@tonyr/announcing-the-winners-of-the-learn-to-draw-with-friends-contest-plus-theme-for-week-four-55-sbd-in-prizes-to-be-won
There are clear instructions on the post by @tonyr, and you can also ask questions on the post if there is anything that you are unsure of. Essentially, tonyr provides 3 options and you can choose to attempt one or more options. You can then create a post detailing your progress pictures and also post your attempt in the comment section of the contest post. Hope that helps.
