Ahh - we can always expect a bit of variation from Emerson. Simple often works very well. Here that is certainly true. Nice division of land sea and sky - plus you have kept the terrain natural. I dont think it needs to be altered, but if you were to id say to leave the land as it is and fiddle around with the sky (trial and error). I like altering the density and thickness of the clouds, and also the position of the sun. - mabye a sunset would look good here. Also a bit of mist wouldnt hurt. There - i think thats just about everything lol. Well formed Terragen!
You're definitely on the right track w/this program :D I do suggest trying to bring the colors out a little..the renders in Terragen always do seem to have the colors seem faded. I do love that framing too :D Nice work!
