Er, I could help there...

The rain isn't bad, it just probably would fit better without, the lightning might be a better choice. There is nice eyecandy, but this looks single player-ish. If so, put some events maybe, I know what events would fit very nicely in here... Probably the food (fruit) events. The tree is interesting use of eyecandy, except it shouldn't only be there. Various other places would work nicely too. Anyway, the screenshot is nice. Could you tell us what gametype it is?
