I think that this bloom effect would fit nice into that level, maybe a bit less but that is adjustible. If you are interested in that effect, contact me with ICQ or msn (my adresses are in my profile) and I´ll send it to you (btw, it is the sylex bloom with some tweaks ). And sorry for the cbabe^^.
And, yeah I would love to see the mystymood water in there.

Looks very good so far but maybe scale the "grass" texture a bit smaler
