I don't know if everyone else has already seen these, but I recently stumbled upon these pages. If the link doesn't work, simply use Google or Yahoo and type in "Toth critiques" and you'll find them scattered all over the web, at various sizes and resolutions - some are harder to read than others. They are comic pages drawn by Steve Rude which were critiqued by Alex Toth. Alex is well-known for being brutally honest and these critiques are no exception, but his analysis is really spot-on and all of his suggestions are attempts to clarify the story and make it more dynamic and interesting to the reader.
Again, I can't help but be reminded that a lot of what makes a drawing succeed or fail is how well it is organized. All of the elements in a picture have to be arranged well in order to put over the idea to the viewer. In writing about the first panel Toth is listing the elements in the frame and after the word camel he adds parantheses with an exclamation point and a question mark (!?) which I take to mean that, due to the way the panel is organized, you can't really tell that it's supposed to be a camel. The way the camel is lying down, the way the stuff on the camel's back breaks up his shape and confuses his silhouette, and the way the palm tree seems to be growing out of his neck all make it difficult to tell what the camel is supposed to be without extra work from the viewer. It's obvious that Steve Rude is a fine draftsman but many of the complaints that Toth lists are areas where Rude's organization and composition have lead to confusion.
No matter what, Toth's writing is amusing to read because he's so relentless in his criticism and becomes sarcastic quite often. How lucky we all are that the internet has given us a place to see and learn from things like this. Very few of us would have ever gotten a chance to have our work critiqued by Toth in real life, and even if we did, his criticisms might have hurt our artistic egos so much that we might not have learned as much as we could have.
There's so much great advice here, tossed off - I love how he questions when the last time was that Rude lifted a heavy box, because his poses don't feel very convincing. The last page is full of admonitions about developing, learning and being hard on yourself that every artist should heed. In any case, it's a treasure trove of stuff that makes one wish that Toth had left us with more documents like this. Check it out and enjoy.
UPDATE: Juan Pablo pointed out in the comments that Mr. Toth did, indeed, leave us more documents like this, although it's him criticizing his own work instead of that of others, so it's slightly less brutal. If you go to www.tothfans.com and click on "Annotated Toth" you'll be able to click on many stories by Toth with notes along the side. Once you open up the first page of a story, click on the page to step through the rest of the story. Toth isn't quite as venomous towards his own work but definitely have choice words for a few of the writers and colorists that have worked on his stuff. Anyway, it's great to peek into the mind of such a talented artist, and thanks again to juan for pointing out that these exist online.
