[Advice] About to tell my friend that I have a crush on her. Would it be awkard if I told her 2-3 things that I like about her?

• We've been close friends for about a year
• She has never had a boyfriend
• I have never had a girlfriend, nor told any previous crushes that I like them
• If she responds positively to the news, then I'll ask her out, but if it seems like she doesn't feel the same way, I'm just gonna end with telling her how I feel
• She gets anxious easily
• We're 16 and juniors in high school

So, pretty self-explanatory, I'm about to tell my friend that I have a crush on her. I have 0 experience with this kind of thing, so I'm wondering if it would be weird/overkill if I listed 2-3 things that I find attractive about her, or if it would be taken as a sweet compliment?

For the record, it wouldn't be something dumb like "your butt, your boobs, and your face." I'm probably gonna go with "the way you ramble about things you're passionate about, your intuition (which she prides herself on), and your sense of humor."

Thanks in advance. :)
