Do you think this means he might like me? And what should I do?

After school I was texting my friend who I really really like a lot. We enjoy the same music and both like art and take art classes. Well he kept complimenting my artwork and said my twin sister told him that I would be going to an art camp over the summer and that he might go too. I was excited about that and told him he should try to go if he can. And then he said for his 2D class that he has to do a portrait drawing of someone and asked if he could draw me. And I didn't know what to say really because I got nervous about it. I don't mind if he does but i don't want him looking at my face for too long because you know how things start looking bad when you stare for too long? I don't know if that even makes sense 😣 but I'm also nervous about having other people see it. Idk. But what do you think? Do you think this might mean that he maybe likes me a little?
