I never went to college s o i can't imagine pulling an all nighter but i guess it's good he's still young
Good that he's young tho while he's hyperfocused on art i'd think he'd take advantage of going back in time to take care of himself/eating good food as well as exercising or so (since if you do physical art/sculpting/etc even if a light touch/dexterous hand is good, some upper body strength/stamina/endurance would be good too)
Hope he has a lot of budget, or a stipend, i understand experimenting but stuff like wood carvings would cost a lot if you didn't do it perfectly the first time , or imagine making something 'fragile', and then an earthquake happens lol unless some art rooms are specifically reinforced
