Oh wow! I love your concepts! :D
These are looking brilliant :)
Ernesta! I love the very top one and the last the most. they start feeling GRAND! these set of thumbnails feel much much more improved. So, keep the ball in the air :D P.S One detail sticking out: your floors look like going upwards, as if up the hill, I bet if you looked carefully at the perspective lines and also adjust cracks to be following the same perspective guidelines , that should contribuete to the picture
Adraiana, Lydia: thanks, girls.J.J.: That's a lot, I can actually see what you so I'll try to work out on that!! Many thanks.
