This little quiz should teach you a lesson in that any four random cards are not all that far behind even the best starting hands in pot limit Omaha.
In this particular hand, it's very likely that your opponents are sharing cards. If they both happen to have AA in their hands, you become a significan money favorite. If either flush draw is live, that helps even more.
The 8 in your hand doesn't really help all that much, but you are double suited and have a nice three card combination with the 3-4-5.
The voting on this quiz seemed pretty close, but it is pretty clearly that even in the worst case scenarios the pot is laying you the right price to gamble here.
