Alex Marston came up with a great challenge to kick things off for April. Draw a pin-up girl and use a photo as your background. In this case, your background photo must be of a place in San Francisco. Be sure to have your pin-up girl interacting with some kind of prop that is a part of the photo like a motorcycle or chair.
For instance, you could take a picture of your favorite cafe with the tables and chairs outside and then draw in your character. It would be great if you took your own picture for this challenge, but if you don't live near San Francisco to take a picture then by all means feel free to use a picture off of the internet. Please tell us in your post if you took your own picture or not.
This will be a fun challenge! Thanks for suggesting Alex!
