<human>: Can you provide a brief overview of the text?

This girl, who is also my ex (mostly unrelated) is a very serious artist. She does lots of cartoon-based drawings, portraits, etc and is very proud of her abilities. The issue is that the style she uses isn't really appealing to me and I don't know what to say. 

I've recently gotten into poetry and other kinds of writing, and I will occasionally show my stuff to her and she's always incredibly supportive and interested in what I've done. But then when she spends hours doing some drawing or painting and asks me what I think, I feel like I'm pressured to lie and shower her with compliments.

To clarify, the kind of writing I do is 100% up her alley so I'm pretty sure she isn't doing the same kind of sugar-coating to me that I am to her.

Should I just accept that with creativity, lying to someone about what you think is the best way to go? She recently sent me a picture of a character she drew from a book series we both love, and I immediately saw a bunch of flaws with the body. I told her I liked it and she got upset that I wasn't being excited and tossing compliments at her.

I care about her and want to support her, but straight up lying about some of her art feels wrong to me. Would the better thing to do be to find a way to give her criticism wrapped in compliments? Should I just refuse to lie to her at all? I'm not really an artist so I could use some perspective here.
