So... prepare for a big post, 'cause I just took 8 pics, lol (I left off Apollo's, whose yard isn't finished, and Audie's, who'll be moving out soon and I'll be editing it for June soon):
Flora and Antonio first! Both have newly been moved (and are neighbors, you can see part of Antonio's house in Flora's pic) and have VERY limited yards (but they make up for it in location- they have easy access to the shops, museum, beach, and RS plaza). Both have a tiny seating area, and Antonio has some practical stuff (a ball and clothesline) while Flora has some more of her "flock" (lawn flamingos).
Next we have Raymond and Paula. Raymond's house is just above Paula's (that corral fencing on the bottom of Raymond's pic is the one behind Paula's house in her pic). Like the above pics, they have limited space, but lovely views of the river, beautiful landscaping, and a peaceful and quiet area. I'm personally a big fan of their houses, and am hesitant to move both out in part because of that, lol. Also, the fountain + table and chairs in Paula's pic isn't technically part of her yard, it's just part of that area.
Now Erik and Ava. Neither are particularly close to one another (that orange orchard along the bottom right side of Erik's pic is just above the apple orchard in the top left of Ava's pic) but oh well. They have more substantial yards, with Ava having a full-blown farm. Her home is just south of the orchard and, while it has more space, she also has more responsibility in tending to her farm and the orchard (but Ava loves it and can often be found singing while surveying her crops!). Erik's home is along the bottom of the upper level of the town forest (if that makes sense). It's quiet and peaceful (the wind turbine's are pretty quiet) and there's food to be foraged nearby, which he loves. It's also not too far from the festival grounds, which he also likes.
Last but not least, Whitney and Octavian. There houses are nowhere near each other. But everyone else was in pairs, so here ya go. Whitney has a properly glamorous yard, complete with moat and pool. It's also close to the beach and is probably the fanciest yard in town. But Whitney deserves it, right? And Octavian has his yard on a small "island" in the corner of the map. It's all Japanese-y to match his home exterior. It's nice, but I'm considering moving him out for Sprocket soon and moving the town dump there, lol.
Anyway, yep. Those are most of my yards. I use those Tiny Libraries in everyone yard for mailboxes- I got the idea from someone on here and I think it looks pretty cute!
EDIT: Oh, and here's my current map (currently changing as I finish setting up the summer carnival, lol):
To show how scattered my houses are, lol. I have a few small "neighborhoods" (read- two houses beside each other) but, for the most part, animals are put in areas they fit in. I've seen a lot of islands where all the houses are grouped together, and while that's great if people like the look of it, I couldn't stand it myself. I prefer it to feel a bit more natural, sort of like in previous games where the houses would be scattered around and you'd have to trek around to see them all.
