a fun tip if you cant figure out how to build something in blockland is to google a lego creation of it
so for example if you want to make a castle drawbridge you could search "lego drawbridge" or something like that
That's not always a bad idea, but as Furdle pointed out you can come to issues with scale.
My biggest issue with using Lego as an inspiration to build something, or on how to do a particular part of a build, is that Lego isn't limited like Blockland is.
With lego you can stick pieces on sideways, and have sheer walls that are at any angle.
I ran into this issue when I was building a
Chariot Circus. I used a Lego picture to get a good idea of design, because unfortunately it is a bitch trying to find good art of a classical Circus, without it being rough sketches and measurements of remains drawn in the 1920s.
Using that Lego image I found myself stuck as I copied it a bit too closely, and also found myself completely by myself when having to design a circular end wall, because I can't do the broken-circle style that the Lego set does.
The biggest irony of all that was that just the other day I picked up an amateur history book (with flip over then/now pages) that depicts a good artist's impression of a Circus in great detail and realism. But as far as I know that image isn't on the internet.
That's another good point if you're looking for inspiration. Google is great and the reserves of images on the internet are fantastic.
But it doesn't have everything. You will find countless images in books and on postcards and newspapers, or even images you see yourself while walking around town, which you will never find on the internet.
Definitely consider looking through books at a library, or going for a walk through town. Bring a camera with you and get some lasting shots with all the detail you need.
Or even look through some of your families old Holiday snaps. You never know what you might find.
