if your goal is primary Sounddesign, there is much missing.
in this racksize, to much modulation
(your bottom row is gone for modulation.)
the Captain O is redundant if want to process extern synths otherwize its just another modulationsource
if you dont are on a small budget and must rely on Behringer stuff, there are other incedible options, at least for the Sounddesign part.
You may focus on either junction or abacus or the doepfer adsr and drop the rest.
same for waves or four lfo.
the sounddesign capabilities of this rack are very limited.
you may look for modules which combine several ways to process audio in one, like waveshaping, saturation, filtering, delay, feedback and so on.
Also a nice filter for pinging.
if you want to go the low budget route, you may get a much bigger rack for the big sized behringer clones.
but I would invest in 1-2 more high quality modules for Sound-Design.
like Malstrom Wyvern (Filter+ Saturation) or intellijel Sealegs Delay, reverb, saturation)
