Yes, it's the return of Wednesday Previews! This week, we've got a glimpse of Dynamo 5 #21. My good friend Yildiray Cinar is helping us out by drawing half of the issue. Mahmud will be drawing the other half, of course. Yildiray also helped out on issue #15, and his work meshes very, very well with Mahmud's. As proof, take a look at these two pages by Mahmud, followed by two pages by Yildiray.
