Greetings, i am a graphic designer and tattoo artist. I have some limited comic designing experience, although this is just a cover-like image and it should be even easier. I am also proficient in traditional art styles (carbon drawing, painting with watercolor/acrylics) so i can make sure you'll get the style you're looking for.
-Is it going to be a heavily inked black and white illustration or full color?
-Do you have specific references for the elements you want the illustration to include?
-Dc is a big company with many titles, are you referring to the style of a specific comic title, or the general "comic book hero" aesthetics?
If you have any questions i'd be happy to answer them.
Thank you in advance, Stratos
