Hey Baruna! Nice piece, here are a few things I see you could work on. First is the overall composition. When designing a comic cover your art needs to fit within the layout of the comic title information. Most comic titles are placed at the top 1/4 of the cover so the name is visible or even sticks out on a wall of other comic books. Your main character's face would be completely obscured by a title in this case. That said, both of your main characters are pushed to the extreme corners of your composition, and they're getting cut off which diminishes the impact of your action. Focus your action and characters using a basic rule of thirds- break your pages down into three even sections horizontally and vertically and place your most important information on the dot where these lines intersect. I placed a rule of thirds grid over your cover design so you can see where your figures are placed on the fringe in the composition, and then placed the same grid over a favorite Frank Frazetta piece that has a similar action as your cover. In the Frazetta piece notice how each of the important character elements are fully visible, and fall directly on a intersection of the grid. This is a good starting point for composing images, so try to keep all of your important info around these target areas and don't let your main characters get cut out of frame. You have an interesting character design for the baddie taking a boot the the head, and I'd love to see how that creature takes the IMPACT of that hit! You didn't tell that story with your picture. Take a look at the zombie recoiling from that huge punch in the Frazetta piece, you FEEL the impact of that huge swing. Ultimately your cover needs to sell the story that takes place in book. It should offer a peek into the action that will pay off if the reader picks it up. By cutting off the figure of the baddie getting hit lower right, we're missing out on a huge portion of your visual storytelling. Hope this helps! Keep up the good work
