Sunset

[Pleymo]

I did want to try something different. I only used default brushes, and some filters. Maybe it doesnt look very good, but just to try ^^

it's hard to see what it is. You need a little atmospheric blue at the top of the sky, and more reds at the bottom. If that's a lake or something then add some greeny highlights. It looks like random lighting to me.

looks good
keep working on it though
perhaps a few ripples in the lake

looks good for just brushes and filters, but i have to agree that bottom part needs more work

[occulust]

is the stuff at the bottom the reflection? cuz if it is shouldnt it be upside down?

[Nightfire]

I think the top is the sky and the bottom is a lake? If so for just the default brushes it's done vary well, though I think the sun should be lower on the horizen and the lage a shad of blue. Also mabe the trees, if the black smudges are trees, a tint of green. All of these colors vary light, just so you can make out the seen a bit better.

Also one of my hang ups are logos :P or some type of symple design for your name.
