Heya! I don't really have anything in the 2:1 ratio department; what you see in the screenshots is what I make. The items you'll find on Patreon snap together on a 32x32 grid. The older items made for RPGMaker (Medieval Town and Country, Interiors, etc) are on a 48x48 grid. Each wall piece for the 2.5D items (basically everything since Patreon) fully occupies a single "tile" space. I do not really do custom work since it tends to take too much time and it would cost way too much for most people if I were to charge them fully for my time, so I tend to avoid doing it at all.
