I've shared this thing on my profile in VK already, so why not share it there.
Here is the downloadable PSD. of my latest illustration, all layers preserved. The quality is lowered, because this file should be used not for editing, but for reviewing. If you're interested in how many layers are in this pictures, how do they integrate, then this link is for you.
There are even sketch layer and basic colours layers preserved.
(Sorry for bad English, you can always correct me)
