MOC parts with the exception of Astronomy Tower (that's my creation) were designed by Gobsmack and you can buy them on Rebrickable. Take in mind that all of these MOCs were modified to fit the current Hogwarts system, most notably I swapped the roofs for dark bluish grey and adjusted the height.
The original version of the Clock Tower from Gobsmack was significantly taller. I had to remove one entire floor and make the roof smaller so the scaling to the rest of the castle works.
It took a ton of work to make everything connect perfectly but the result is everything I wanted it to look like. Almost entire backside of this castle is built using MOCs by Gobsmack which I modified to fit this newest Hogwarts system. The Astronomy Tower is my own creation. More renders from different angles soon.
I'm sure I'm not the only one who just wanted to create his own GIFS and be able to find them on Instagram. Well it turns out for that you need to have "Creator Account" upgrade on GIPHY. I was like cool, let me get that, I applied, I fulfilled all their criteria to be eligible and guess what day later it got denied. After reading through discussions all over reddit and youtube on this topic I came to conclussion that for normal mortal that is not some kind of influencer or big brand it's nearly impossible to get the creator account. Anyone here has similar experience and is pissed at GIPHY moderators how picky they are and refuse over 90% of applications?
