I don't know much about sigs, but I really like this one toriabiz.
Does not seem a lot of filters as several people do.

Also, need to finish the beard, but what you think?

tiny skinny beard
needs moar beard
less yellow, moar blonde

otherwise its fine

I need to finish the beard.
Moar blonde?
Also, improving the helmet, is a bit empty.

I think it looks good so far, some hair underneath the helmet may or may not look good. I don't think very many people got as yellow hair as that, but it do match the helmet :P horns look good, continiue (:

Finished. Thank you Ezeth.

it is a simple vector, You have done it really simple.
I dont much difference of your previous ones.

Batman WIP:

old man mouth
the batman ears dont look like batman ears, rather batman eyebrows

otherwise technically excellent, it just has no character.

Eyes are looking upwards.
And as bendover mentioned the ears look like another pair of eyebrows.

corrected some things.
made the chin.
lacks texture, beard and mouth is unfinished.
about the ears, thats the highlight of the light bouncing there.
I made it this way cause it is bounching trhough the entire face of the ear.
