A writing sample would be appreciated to make a better assessment.

However, I'd like to state my own view on the topic. I don't feel this is a gendered issue, and from first look it seems like the accuser attempts to make this the case. But, I can't make that judgement either so I will stay away from whatever fierce discussion that ensued with your ability to write the female character.

Focusing on the looks of a character is not exclusive to female characters, as I've seen plenty of samples where male character looks are overly emphasized. Most of the time, if not all of the time, I'd say that's a novice writer's mistake and one I make myself at times due to laziness if I write far too quickly. 

I don't find there is a bad at writing 'male', 'female', 'black', 'white', 'gay', etc. type of character. There is only the writing of a poorly developed character. 

My advice? Try not to get too prickly with the opinions of others. They may be strong, and they may say things about your writing regarding female characters as 'cringeworthy' or 'offensive'. The implication of offense rings hollow to me as there are many who consider the depiction of female characters on Game of Thrones to be 'offensive' when I'd say they're some of the most rich and intellectually diverse cast of female characters within fiction. 

Read more books, watch more films, look into advice columns (and other types of media) about writing different types of characters. It's your creation, your imagination, and your character. You will encounter various opinions about your work: NOT ALL OF THEM ARE VALID, including mine. All I care about is whether I find your writing to be of quality, not whether your characters fit my pre-determined biases of what a character of a specific type should be.
