Oeeehh starting to look muuuch better, I guess you could maybe have more tileset variations, like try using the "Ruins" sand and stuff, since it's under the water, but that tileset looks fine right now though...
Anyone else got some advice?
EDIT: I think you don't really need advice in my mind I think every terrainer is their own artist and you create something that you've imagined, and no-one can actually see what you have in mind, people can give pointer that'll look better for them, but I guess I can give a few more....
1. More coral reefs, bubbles, ect. just go look under water, there are MANY variations as you can see in my pic, just play around with them in the pic and make it more... Underwaterish
2. A little more fish wouldn't hurt
3. Get a "Big Daddy" to walk around in the water.... (would be cool for me ;P)
you are a good terrainer, and I'd +rep you, but I gotta spread the rep a little more before I can give you again :( |
