Rofl. Awesome heads.

How close is it to being finished? :O

Err, I only made those pieces, I need to fill up the entire head.
Then I need to add color and some unique features.

I'd say around 10-20%.

Is it gonna be all colourful? I quite like the greyness

I luv' 'em. Also, i like the gray too, but some toxic eyes could maybe help? Idk, just a suggestion.

Nice ;o
Kinda looks like an eagle face too =o
mechanic demonic eagle :B

eyes aren't nice
Make them blue or white

your eyes arn't nice!!
