I'm working on this Hedorah-esque figure currently referred to as "Reading Hedorah".

What kind of spray should I do for the various colors?
I think a spray on the eyes and possibly the sides and maybe a contrasting wipe. Metallic blue on the blue, Metallic silver on the red and yellow, gold on the brown.
Any thoughts?

Any colors I should do? There's also a black and a green.

Ruh roh!
Pretty cool sculpt but I don't think you did enough details to show it's a Hedorah IMO.
How big is it?

He's less than 4". I simplified the sculpt quite a bit because I like it a little smoother. He's supposed to look more doughy and less menacing.
Here's another view of the Red. It's cast hollow and clear so it really picks up the light.

it looks like he is giving a sermon

Yeah it does look a little sermon-y. I think that just goes along with the ridiculousness of the figure.
He's actually looking down at the book but you can't tell from these photos.
Here's a yellow glitter version. I'm not sure about this color.

the arms look a little awkward... are they glued on?

They're both pinned and the one holding the book is glued. I think the angle of these photos makes it look weird. The other arm is articulated and that's part of why it looks odd.
I forgot to mention that this is resin-cast and the arms are separate from the body so they don't fade exactly the same.

Edited for douchebaggery

uh...noted?

I always miss out on the douchebaggery...

i was down with it.

Tried some gold and metallic pink sprays on the brown. He's lit with a flashlight to show the clear fade.

cool figure--I like the book, nice touch.
Given the details of the fig dry brushing or
a wash with black followed by dry brushing
would make the lines pop a little more.
The translucent quality is cool.

this last one looks pretty cool.

the book gimic is interesting.

"Father Smog, forgive me for I have sinned"

He looks like a Fry Guy

Story has been edited. It's my version of a Hedorah-esque creature.
Thanks for the notes. I need to do something because the paint is still looking a little flat.

they might look better if they were glossy

and i think it looks like he is performing an exorcism

I'll probably do a glossy topcoat. The black resin tends to shine more than other colors. The brown is probably the dullest.

That ruined it for me right there.

well...I don't have an agenda. I just thought it would be funny to put Hedorah in ridiculous situations.

i like my story better....
father smog is a preacher who has butt sex with unwilling altar bemons

Ruh roh!
Butt seks.

That would be a ridiculous situation.

no more so than a reading hedorah... his eyes are sideways for craps sake... how could he possibly read?
my story is way more plausible
