Nice to see you've gained an Interest in the
best development known to Graal! (Leveling)
I've circled a few minor mistakes, but it's still a Good level.
Yeah I did not know what to do with mistakes 1,2,3,4. Can you show me what I could have done because I don't know lol.
Yeah the level was just a basic one, I just wanted to design a simple house. Thanks for looking out for me though.
1) Tile Error: The Roofing is meant to join together here.
2) Tile Error: (Same reason as 1)
3) Tile Error: (Same reason as 1)
4) Tile Error: (Same reason as 1)
5) You used the wrong tile here, you did it well on the other side.
6) Looks like you just placed pavement (Randomly), Try and make it regular.
Other Tips:
-Add more NPC's to your level: It looks kinda Bare and boring.
-It's good to see that your level isn't a box shape like my first level, but investigate with other shapes.
-
LET your imagination gooooooooooooooooooooooooooooooo 
-The Porch idea at the top is good, but just add more pazam to it.
