um, I don't know why it is so dark for you guys, the sun is at 30 degrees and, on my computer at least, the image looks like it is at noon. I'm guessing this is a result of us having different computer/monitor setups, if I could get your settings then I could do a better job of producing a better image for you guys

The flowers are actually from a flower pack from ashundar available in the download section, here is the link

I should have mentioned this earlier but the grass is from Lightning, thanks dude your plants are just awesome
