The map is great, but the excessive amount of decorations and world-shaping is going to play up. The deco distracts you way too much and will cause lag HELL; world-shaping will take some time to get used to.
When making maps you should focus on visibility, playability, and flow; decorations should take up ~20% of the map, not 80%.
If I'm going to be honest, this is more of a show map, rather than a race map.
