Dont forget we have a gigantic gallery on this site. If you want to dive in and see models, just go here:
to load a random image. Voting on the image (upper left hand side) based on how good the paintjob is (N/A for unpainted), and how cool the model is, will provide valuable feedback to the uploader and will load a new photo for you to view. The gallery rotates between stuff everyone thinks is cool, stuff nobody has voted on yet and completely random images. Provided you are logged in when using the gallery, you will never have to see the same image more than once.
