Wow, impressive process, however two things are interesting #1 why is it that every little pill and crack in the bottom is painted but the hands have no fingernails defined? And #2 actually the shadow is right everywhere, except on the wall where the roses are close: objects that are near to the ground cast a sharp shadow. It might be a choice but a variation between sharp and fuzzy would have helped to add to the realism. But actually that is nitpicking on a very high level
Not sure why you'd go to such great lengths to emulate the aesthetic of a 3D render (it really introduces to the image a certain kind of artificiality or 'poorness' - and I'm speaking of this piece and a few other ones - which is induced by surfaces looking like they're all covered in cheap formica laminate/cheap texture maps, or simplified cuboid or cylindrical bodies; though probable, this still throws people off, because we have knowledge of bad renders, and expect 'real' objects and materials to be much more complex), because you clearly have the skill to do otherwise (or to not have to push it to such a level), and it doesn't seem to be your intention to engage in some kind of critique regarding perception and the reading of digital images and whatnot. But well, whatever floats your boat.
Wow your works are amazing! I am trying to go into super realism too, but just with portraits. I don't think I have the patience for a whole scenery haha. Can i ask you something? Why do you neatly fill in the colors on slide 3, only to repaint it differently one slide 4? Is there a reason you do that? Is this all done using pure painting, or do you use photoshopping too?
