Slightly different style (more bendy/curve) but I like it, and pretty polished already!
The 3D-DNA/visualise and assemblyation_status corners should be curved somehow rather than the hard right angle - it's a bit jarring currently (the amount of curve of the orange line might be sufficient for these two)
I would increase the size of the station circles a bit, they are a bit too small/ratio to the lines is a bit off to my eyes
The FASTA/TSV going to MUMmer Circos plot is a bit hard to infer if that's input or output (I'm presuming it's input?), it should be angled to indicate a right-to-left directionality if so (as in push the mid-point of the curve angle in the direction it's should be going so it's not the center of the black stop bar). Another option is to change (for all inputs) the bars to an arrow shape rather than the bar
The black stop bars ratio is also a bit off, I would make them all a bit wider (except the final AssemblyQC HTML - that one looks fine to me)
