You did a fantastic job with this. The lines are great, and appropriate for the characters shown; The value is also good, making proficient use of hatching and contour line techniques, as well as non line based shading.[Color darkening, esc.] The colors chosen are also good as well. A few minor complaints would be that Venom appears to be floating in midair, and the background seems a bit strange to me. However, on an overall scale, this is excellent. It's no wonder why you almost sold out of print at Comic Con.
