From which blocks to build? Minecraft?

I want to rebuild the whiterstorm and the colossus of minecraft story mode. Only from blocks. Which blocks do I take for that? At whiterstorm I thought obsidian, that's good. And what do I take for the colossus

Can you show pictures of this whiterstorm or the kollos? Then i could help you am ultra builder in minecraft.

colossus

Have pictures sent here as an answer

At the colloss you should limit yourself to prismarin blocks or other azure blocks, as you can see prismarin blocks in the picture. The whiterstorm I would use with the new colored concrete blocks from the 1.12. Or also carbon blocks or black wool.

And the eyes of the whiterstorm? Purple block and ray of purple glass? And I get the eyes somehow to shine with both

Put beacons behind it
