the first screen is nice, but a bit small looking. personaly, i would have a much larger outcrop of rock in the center of the screen, and take the screenshot from further away. that way the tiles would look less blury and square formation, and the hilltop would look more realistic.
in the second screen, again i think the scale of the terrain is too small. scaleing up the ships, and remaking the terrain larger would mean the pinnicals of rock, sea texture and floating ice would look a lot more detailed. also, this pic is somewhat lacking much of a background |
