Smooth Edges From Loft?

So I lofted some curves but they edges are really rough. I tried using some weaverbird components but the didn't really help out that much because it removes the mesh from the edges of the voronoi. I tired just bringing in the mesh into Rhino to smooth the mesh out but that didn't help out either. I attached my definition, a screenshot of what I have and a picture of what I want to make.

Thanks in advance!
