I have been looking through the sketches on the link that I posted, and so far my favorite site on there is Pencil Lines. It is a sketch challenge blog, so basically they upload a new sketch every week and see what people can come up with. Right now I'm not really looking for a challenge, I am looking for guidance and some inspiration, so I didn't use the current challenge sketch, I browse through the previous sketches to see what I could use. For my Pirates of the Caribbean Page a few posts below I used Sketch 113 . Sometimes it is hard to see what you can come up with with just a sketch, thats why I like that they post some layouts done with the sketch to give you a better idea.
