Make it into one portait of the masked man wearing a black skull mask, the teeth needs to be detailed and the clothes and head extended so it's one panel portrait only. Remove the speech bubbles too. Keep the original skull design and angle, with the man's skin visible in the neck . The head should be slightly title down for sinister mood. The teeth grey but a bit lighter than the rest of the mask. Keep the exact same color palet. Make the eye holes into black tinted lenses
