This is not at all meant in an unkind way but the United Kingdom of England, Wales, Northern Ireland, and Scotland is not welcoming international scholars right now, particularly in the hard humanities. The Fulbright was a tiny tiny stream of funding compared to Erasmus, MSCA, and DAAD, now all lost to Brexit. The UCU is on a staggered strike this week, students, faculty, and contingents. Glasgow is a rubbish city, overpriced and unfriendly with a disproportionate rate of violence. If you are studying a specifically Scottish subject, think about Edinburgh which is the art history/architecture powerhouse, but there will not be a funding stream for an MA program. The British system MA is research-only and very isolating for international students, in addition to being vastly overrated. Almost any R1 in the United States, any land grant, any public ivy with an art history MA (particularly combined with good MFA programs, such as at a lot of the NY, CA, and MI systems) would offer a better program and better chance of a scholarship, plus you'd be able to get experience as a TA or GTA at some point. Good luck.
