What's that blue ball here ?

Something is coming (and that's not winter, we're already in, duh)...

It's a huge project that I have in mind 5 years ago, but I didn't have the skills for drawing and many other problems, and I still have them. I prefer the drawing solution since the Universe is already pretty complex and very original so it's for sure a very hard task to me to describe it by writing. I think I'm gonna ask for help here (because there's a lot of talentful persons on NG ;D) but not now. 

I also made some others teasers but I didn't post them here because I don't want to post teasers everytime for nothing, and because NG is mostly made for finalized creations (even if it accepts WIPs, I still prefer to upload final versions).

The other teasers :

The same ball but with heads and glowy eyes in it. What does that mean ?

Who the heck is this guy ?! And why he is made of cubes ?

Feel free to ask questions if you want to ! I'll manage to answer them as quickly as I can =).

PS : Nope, no 3D will be used because my computer is not powerful enough to manage properly multiples polygons at the same time. Maybe Pixel Art...
