Sitting at the day job doing a bunch of glass pieces that take 20+ minutes each to engrave so I'm doing sketches with room pix from Ikea's website as reference while they run. Mostly this is going okay, and then things go pear-shaped. Like in this kitchen--counters, fridge, cabinets, all fine. Then there's a piece like one of those cabinets that sits in the corner of the room and my brain just bluescreens.

fucking perspective, how does it work

(yes, I know, just do it, practice moar, git gud son, etc. etc. but shit on a stick this drawing thing frustrates the hell out of me sometimes)
