Nova you have really cool ideas for maps. Even looking at your submissions for the mapping contest you always find ways to make the map interesting either visually or for gameplay. I like Salt Quarantine's dropping salt towers, Deep Glacial's spring panels inside hot craters, Golden Passage and the sneaker panels being sync'd to the music, and the hovering sections in Howling Bogs are a neat way to handle multiple higher paths.
The layouts can be fun to drive on too! I always enjoy seeing more snow/ice maps and Deep Glacial has some good ice placements! Salt Quarantine can be fun but I feel has way too wide of open space to drive through. Players can just stay away from each other easily to avoid item interactions because of it. Howling Bog's first cave entrance is cool, but I feel like some of the texture usage can appear to be a tad "busy" where it is a little hard to tell what is going on. Brimstone Ruins at worst I feel pretty neutral on, so good job there. Golden Passage I'm not sure what the point of the waterway is for, since it seems slower than the normal road and feels like a way to trick new players unfamiliar with the map.
All of these maps are still of very good quality. It's great to see how far you have come as a mapper!
