Lol, I just noticed now that you mention it, you are right :)!

the kings and queens are all on the wrong squares! :(

very good!

Anda es vdd! De hecho al principio los tenía bien si no recuerdo mal, dado que después cambié las bases de ambos xD. Gracias!

¡Muy bueno! Pero la iluminación en los caballos está al revés, prueba a voltear las bases.

 Oh wow, great improvement! :)

 It looks better now, thanks :D!

 Thank you a lot for your suggestions, I'll work on it and see how it looks :D

 Good handling of value, but I think a little hue-shifting and dynamic light will take this work so much further. Try getting rid of all that greyscale [greys tend to make an image look static] and substitute them for some desaturated blues [shadows] and saturated yellows [highlights]. Also maybe shift those shades in the purple towards blue.

Looks great, there's a lot of technical detail here to be appreciated!

 Thanks!

Nice textures.
