That looks A-OK all around, though there are a few minor things you could change. For one, add some more Spikerocks to delay the Gargantuars earlier. And instead of the Umbrella Leaf and Gloom below/above it, make those Fume-Shrooms. That way you can damage the groups of zombies more, especially on the outer lane. That's about it, good luck!
