really love that one - lots of character
Inspiring workflow for both the process and the presentation.
Admire your work alot, especially the finely carved in details
ontop of a great silhouette. ItĀ“s amazing how well the colors
help it come out even more, too. Including the backdrops.
Cheers

hey david!
great stuff. i really like the hard edge design.

The alien is a really cool design and nicely done! I like the hard edged angles and shapes. Really gets my imagination wandering, thinking about this characterās backstoryā¦
Great design, this guy made me laugh for some reason dont know what.
Woa. Great execution and design. That one mat cap resembles a really good sss shader. really nice.
Keep the cube aliens cominā¦
awesome sculpt david! Great design! Could we have any time lapse videos ? 
Really Really Cool! How do you render in zbrush? how do you define the specularity? I always love your characters. 
so cool! great style.
Awesome shapes! Love the render style as well!

awesome, the teeth are insanely good looking, love the neck muscles too.
i prefer the first head, this one doesnāt look organic to me. Iām sure you did it on purpose but i am not sure to understand what he is made of, could be a exo-squeleton mixed with some shell kind of elements. bah Anyways all in all, i think it would looks better with a little organic touch, like strech skin in some areas etcā¦ just my 2cents it looks great nonetheless
quite unusual alien, i like this!!!
i want the same shape of the head 
Way Cool !!!
its great ! love the colors that you usedā¦
Thanks a lot guys!!! sorry for the late reply, I started to record a timelapse but I crashed so I gave up on recording! (for this time).
Nicolas! right I want the shape to be pure for this one just the form Iāve been doing a lot of hyperdetailing back at work so I wanted to depart from that a little! 
I also want to thank Damien Canderle for his wonderful brush http://www.zbrushcentral.com/zbc/showthread.php?t=57944&page=6&pp=15&highlight=maddam+brush
a few poses to close his mouth
