I mean.. HOW?! With the eyes my golden sharpie's tip is still too big for the eyes, what can you suggest that i could use, Or how can I color the eyes & teeth.. I really need to know
Update: I went to my local book store and found ultra fine sharpie markers in the color of tangerine and I think it's orange (Dark shade of orange) do you think it will fit, well, at least one of them like if you watch the movie, at the 1:54:05 mark as Godzilla was looking at Serizawa (I can't upload the image since it needs to have a link rather just upload)
