I created a quick little monster sketch on my ipad using adobe ideas!
I created a new layer and placed it above the little monster sketch layer. I turned the opacity down to about 40% and started coloring. I always make sure to then bring the color layer back to 100% and check how my coloring is looking.
I turned the color layer to 100% and hid the sketch layer. Now it is easy to make changes or add to the image. This is still needs to be touched up but I liked the over all look!
I decided this little monster needed a girl friend. So I copied my monster layer. (oh I think I forgot to mention it is sometimes good to create layers for different parts of your illustration. ex. I put the hat on a different layer). I then added a purple bow, made eyelashes and changed the girl monsters glasses to pink along with her socks!
