Alright! I can gladly say that after much work today, Selkirk County is finished! The work today wasn't so much from the houses than it was from trying to get the world downloadable, to be honest. Apparently I don't have a network (...?) to upload Selkirk County onto the Exchange, so I wound up putting it on mediafire instead. Link is here: http://www.mediafire.com/file/2e0u2cfpe2sn03h/Selkirk_County_%2528Beta_Unpopulated%2529.Sims3Pack/file
As for those last two houses, I'm really happy with how they turned out. The first one is called Veranda Manor and it has five bedrooms (one more than Crumplebottom Manor, I realized after building it) and four and a half bathrooms.:

The second and last house is called The Tree House and it has four bedrooms and three and a half bathrooms. It's slightly similar to Veranda Manor, but not overly so:

And here is an aerial view of the world that I used for the thumbnail picture! It's a nice after picture, if I'm being honest:

The before picture, in case anyone didn't look at the imgur album:

Getting this world uploaded onto the internet took a lot more of the time that I had than I expected it to (2+ hours), so I didn't have time to test it out myself. That is the goal for tomorrow, hopefully. If the download doesn't work for some reason, please let me know, although I might need instructions on how to fix it because this is not just the first world I've made, but the first thing I've uploaded onto the internet besides pictures. :sweat_smile:
Oh, and one last thing: thank you all for your comments and general support! It's really meant a lot to me! :blush: And a future thanks to anyone who has decided or will decide to test out this world!
