I would remove the sword and let everything grow for two weeks, then remove and replant in tighter bunches. It looks really chaotic in there and your eye is probably wanting some sort of focus. Most of the plants are growing in and amongst eachother causing the aquascape to lack definition. Replanting in tighter bunches will help give definition to your tank. For starters try planning your planting with all the plants in triangular groups. Occasional replanting in geometric bunches is a good way to practice planting technique and will help build your "eye". It's amazing what something so simple can do for an otherwise healthy and vibrant aquascape.
