This week, in order to celebrate the upcoming 13th B'ak'tun; you are challenged to create an isometric piece which depicts a Mesoamerican pyramid, or a pyramid inspired by actual Mesoamerican pyramids.
This page should be helpful.
Canvas Size - Unrestricted.
Colours - Max 21.
Transparency - Optional.
Animation - No.
I'm not going to do anything. The world will end next friday. 
I wish I would be able to see the outcome of this challenge... Can't we start the voting already tomorrow maybe?
>I don't think I've encountered nonstandard iso either irl or in pixel.
IRL = 30 degrees ("Isometric" itself means 30-degree lines; we've just expanded it to include any useful dimetric projection.) 15-degree dimetric (shallow view) and 30-60 (pseudo-oblique) are also popular for product design.
Pixel-art dimetric = 1:1, 2:1, 3:1, 4:1 (among others). Boktai is a very popular 1:1 isometric game. Many games on c64 and amiga used 3:1 and 4:1; shallower angles became less popular as days want by though.
Live a little bro!
EDIT : sticking to 2:1 for the challenge is fine. just pointing out there's lots of other systems!
I see your point, but stick to the standard 2:1 / 22.6 degree lines. I can just see this opening a can of worms in future challenges and collabs :/
And honestly, I don't think I've encountered nonstandard iso either irl or in pixel.
not line angles, but rather compression ratio (camera pitch)

^ the trouble with any of these middle pitches is that the steps butt into each other. A view that is closer to side-on or top-down (while remaining dimetric) allows you to show the plan or the profile better (for this particular shape).
Are you talking about the angle of the sides of the pyramid? There's no need to stick to 2:1 there (outside of beiing anal about nice lines I guess). These mesoamerican ones tend to be step pyramids anyway.
And i thougth i would have problems with this XD <---- noob
maybe the ratio will be based on our own preference?i used 2:1 for the angled parts; they served me nicely.
Does Isometric require that it be 2:1, or can we use another ratio? (Pyramids are notoriously nondescript in standard videogame isometric - a steeper or shallower angle is preferable).
well okay than...isometric?---meaning blocky and in shape right? 
i still mess up with knowing icometric from non isometric,and basicly we need to draw a pyramid and add some stairs to it and windows?

Well, I was trying to see if I could do a piece in the four hours I had before work, however, my inexperience with iso made it rather irritating and there ain't no chance I'm finishing in half an hour before work.
I also cannot use my photobucket, so I can't even show a WIP. =(
