ather shahzad assistant is not a bad choice but i am not too sure of red. so i think u should stick to madiha assistant. i doubt sifat touch up would make any difference. also my cousin recently had her makeup done from sifat. i will tell u a few things abt her makeup . she looked pretty good in person but not so much in pictures ( this i have been noticing a lot with make up from madeeha's) the problems that i found in her pictures were:
eyebrows looked to dark
hair looked very chipkey huwey. (no volume)
her eyemake up wasnt complementing her eyes if u know what i mean. like her eyes are quite big , the eye makeup was really good on its own but on her eyes it just didnt come out that well. it made into a completely different person. changed her shakal which is not the best thing for a bride.
she is dark and sifat tried to make her look very pink :S
ahh i dont know. i hope this makes sense. these things reallly stood out in the pictures, however not in person.
