Try it an find out!
Seriously, the standard answer to the age old "what order..." question around these forums is "it's what you like best." There are some general ideas that people tend to stick to like "compressor after envelope filter" or "ambient stuff (delay/chorus/phaser/etc) at the end," but... everyone's different and likes different things. There aren't really any hard & fast rules.
So... give it a try and see which you like best.
