I am very much a newbie who does not invest in .com, but here are my thoughts.
Although I don't have good ideas about potential users, I like the short ones that all seem to me to feel modern and potentially good uses for a startup:
bernx.com
orlion.com
sultao.com
As has been mentioned, orlion is a nice contraction of two Orion and Lion (a constellation and a translation of Leo). If trying just one for now, I might choose it.
Between unproclaimed.com and unacceptance.com I prefer significantly the first. Although unacceptance is more widely used, it seems negative to me, whereas unproclaimed is potentially positive.
I like twivue.com almost as much as the first three, and maybe it would sell better as a contraction of twilight and view if you could find a buyer who was, for example, into the right genre of films or books or maybe other things.
Whatever you decide, good luck! Thanks for giving us the opportunity to express an opinion!
