a version of a vision by ~PlugInFiend on deviantART Spoiler the eyes are a little odd as i failed to get the depth correct. what are your thoughts?
if you go to the deviantart page, you'll see a link to what i used as reference. the eyes are waaaay wrong. they should look out of the image, but they dont and arent looking in the same direction.
Well you need some visual cues to give it depth, shading is really the go-to for this isn't it? Veins would work but not for this specific piece. Look up extreme close-ups of eyeballs, there's some cool stuff in there.
Shading is a definite must, with that try to avoid the use of hard lines on anything except for hair and maybe some areas in the eyes. This, if done correctly, will make the piece much more realistic.
