400x400 clean practice PvP lobby for Minecraft 1.12, themed in cyan and white. Central area: large open grass plaza with scattered oak trees and green leaves for natural decoration. No bridges - instead create multiple floating islands (8-12 islands) of varying sizes (30-60 blocks each) with parkour jumps between them for practice movement. Island style: white quartz base with cyan stained glass accents, some with small oak trees and flower pots. Islands should be empty/decorative only (no mode-specific structures), serving as parkour practice obstacles. Main lobby features: - White quartz pathways with cyan carpet borders connecting central areas - Cyan terracotta and white concrete building materials throughout - Small decorative trees (oak logs with green leaves) scattered around -
