I [16M] am about to tell my friend [16F] that I have a crush on her. Would it be awkward to list 2-3 things I like about her?

Some background information:

• We've been close friends for about a year
• She hasn't had a boyfriend
• I haven't had a girlfriend, nor told previous crushes that I like them
• If she responds positively to the news, 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

So, pretty self-explanatory, I'm about to tell my friend that I have a crush on her. As I have 0 experience with this kind of thing, 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.
