<human>: Could you distill the essence of the text into 1-3 sentences?

So, as the title says, I'm a good drawer. I'm not anywhere near prodigy level, but apparently having a decent grasp on the basics makes me a 'good' artist for my age. 

So, quick background. When I began drawing a few years ago, I got praised a lot (you know, the polite 'oh, that's so good!' kind of thing), so I was driven to practice and become better. Apparently, I passed the mark from 'that girl who draws' to 'that girl who's a really good artist' sometime this year, because I got complimented randomly, and people came up to me to ask me for tips.

I am super flattered and love the attention (though I sort of feel like a fake because of course I would look 'good' compared to everyone else, since I've slaved over my art, while everyone else just went on with their lives...). However, one friend in particular always asks me for help. (uh, rules say that I have to state length of relationship, so we've been friends for 2 years)

I do want to critique her and just help her get better in general. I can see what she has to work on pretty easily (she just has to study anatomy). Unfortunately, I have no idea how to do that without sounding like a pretentious jerk, and possibly offending her. I don't want to lose her over something as stupid as this.

I don't want to walk on eggshells anymore. Please help. :(
<bot>: I'm good at drawing. One friend asks me for advice on drawing. I don't know how without killing our friendship.
