I decided to man up today. In class today, I was coloring, and didn't know how to draw a horse. I asked around a few people, and I saw this cute girl look at me a few times and smile when I was talking. I decided to go for it,man up,and talk to her. I walked up, and Here is how it went

Me:Do you know how to draw a horse?

Her:[Weird smile] No, I don't know how to draw well

I just said oh okay,and walked away. I bombed it,and knew it as soon as I did it. Later,when I was walking to a class, she saw me and was talking about me and I over heard her saying "Thats the guy right there, after I was taking a test.."

I know my body language wasn't strong, and my voice wasn't very confident, just more of an awkward question..But, how can I improve now? I need to get my damn confidence back
