"Destiny (German: Schicksal) is the only wordless novel by German artist Otto Nückel, published in 1926." How about splitting this? You could put the date of publication in a separate sentence with a mention of the publisher and country (both currently absent from the lead) 
 *Two potential issues with the lead image: First, it seems to be quite large. If you are keen to display the details, perhaps you could consider a crop? At the very least, this should be clarified in the rationale. Second, it'd be good if you could provide some context in the caption- I assume this is the lead character murdering a man? 
 *"The images range in size from 2 3⁄4 × 2 3⁄4 inches (7 × 7 cm) to 4 3⁄4 × 4 inches (12 × 10 cm),[8] and were originally printed on thin Japanese handmade paper[7] when it was published in Germany in 1926.[9]" Unclear what the "it" is, here- Destiny/"the novel", presumably? 
 *Was Nückel directly inspired by Masereel? This is implied, but not actually said. 
 *Do we have articles worth linking to for "leadcut" or "multiple tool"/"lining tool"? If not, should any of these be redlinked? 
 *"Lynd Ward found Nückel's book had greater psychological depth in its characters and plot development, and more skilled technical achievement in the artwork." Are you citing Ward via Walker, here, or have you missed a reference? Also, I note that this is the first mention of Ward, but the name isn't linked, but it is linked later. (In the sentence before, Masereel's name is linked, despite the fact he's already been introduced.) 
 *The only two hits on Nexis were for this and this. Not particularly useful for this article, but potentially a couple which may be useful for you elsewhere. 
 *According to , Destiny may have had an impact upon Will Eisner, and, specifically, his development of the term "graphic novel". Apologies if you were aware of this, but perhaps worth mentioning? 
 *I'm inclined to think that a "Works by Otto Nuckle" (or similar) category would be appropriate. 

 Interesting topic. Article seems strong, reflecting the light literature on the subject.
