Woman on Instagram is offering me 4 ETH for four of my artworks each. Is this a scam?

I’m a visual artist that makes digital artwork which I transfer to canvas prints and sell them. On my Instagram page earlier today, I received a message from someone who said they loved my artwork and asked me if they were for sale. When I responded that they are, she told me she was interested in four of them as NFTs and would offer 4 ETH ($7600) for each of them.

I have zero experience with crypto currency, but this seems too good to be true. How likely is this a scam? Could this be legitimate? If so, what is the best course of action for me to take? Any advice would be appreciated.

Edit: This wasn’t a fake supermodel looking spambot but an average looking woman by her pic. Unfortunately I can’t see the rest of her profile because it’s private.

I appreciate the advice you all have given me thus far. It seems the best plan is for me to upload my art to Opensea and see if this person will buy my art for the price they offered on there.
