Looking pretty good, Dallen.
As Curt said, one more discus will be helpful to the social compatability, but 5 is the max number in your tank, particularly with the tankmates you have in there now.
And as JerSaint mentioned, a background would make a nice difference, although I suggest a lighter color shade - you already have a semi-dark substrate and a dark background will make the discus coloration get darker, and you may get some peppering.
Suggest you consider using well-bagged Seachem Purigen in your filter(s) for a while - it will really help polish, clarify & purify your water. Just a suggestion.
Your neons may not last long - they don't do well at all in the higher discus temps - Cardinals are much better.
And keep an eye on your Otos - as they get larger, older and lazier, some MAY tend to take a liking to discus' slime coats as part of their diet.
And Zefrik - why don't you give discus a go - they're extremely satisfying fish to keep.
And not at all difficult, if you get at least 5, in a tank no smaller than Dallens, you get reasonably good-sized healthy specimens from a high quality supplier to begin with, and are prepared to do reasonably frequent wcs, with a good tank cleansing routine.
They need a little more care & attention than most fish species, but are well worth it.
