Hi there!
I am also new, however, the first thing I notice is the amount of space the Hermod sequencer takes up in such a small case. This could easily be solved by buying a bit of a bigger case, or moving the Hermod to a separate tabletop case...maybe the 4ms Pod case
I also see two different reverb units. Just starting out, I would say pick 1 of the 2.
This would then free up/create more space for another VCO to have more wave forms, another VCA, or modulation source of some kind. An envelope module would also be something to think about, a clock divider, or a utility module...such as something for logic or maybe a switch.
