Hubpages is always a favourite destination, but for me the topic category arts and craft has a drawing section which always fascinates me to see many new hubpages there on how to draw certain stuff and other drawing articles with step by step content.

I've had a little go myself there, so why not have a go, you can write about art and any other category type that you have an interest in, so give it a shot and see if it boosts your traffic.
