This is the cover art for the single of the first opening theme, so the artist might be Oota Kazuhiro, the character designer of the show. This is not guaranteed, however.
Also, you can get a better version here. It doesn't look like it on the page, but it's actually pretty high resolution.

Thanks for the additional information! Interestingly Rei and Miyako have glasses in the version you pointed to and they don't have them right here.
