Wow, I like your version, It's actually a very good translation of the lyrics.

I have been reading the russian lyrics and trying to figure out what you can write in the missing parts...
for example here:

??????????????
??????????????
O decir algo
Sin romper promesas
Y sin poder mentir

it may be:
es simplemente el reflejo de
nuestro sexo incorrecto
es decir algo
Sin romper promesas
Y sin poder mentir

or maybe:

es sólo el reflejo -
el sexo incorrecto
es decir algo
Sin romper promesas
Y sin poder mentir

I dunno, it's kinda hard to translate literally from russian to spanish and make it sounds good in the song

Finally, a small correction, when you say: "Nadie se rindera" it's actually: "Nadie se rendira", it sound slightly different .

Anyway, very good work I like it.
