Help Build the new Highmark stadium in Minecraft

On the server earthmc, I am building the city of Buffalo, and I need help building the new highmark stadium. There is a schematic for it that I can get the link to. I mainly need help with terraforming around the stadium and leveling the land, since there is someone who is going to build the stadium but if anyone is a good at building from schematics on litematica, help with building the stadium would be great. I also am planning on building Keybank Center like I did in the previous map. If anyone is interested, the server ip is join.earthmc.net. When you log into the game you can do /t join Buffalo in the chat to join the town
