Thank you everyone for the comments & suggestions. Please feel free to critique harshly - helps the work since often I don't know what the next step is.
All you need to work out are those clouds, which already look far more like real clouds than any others I've seen. Don't change the water color at all - the simultaneous air/sea effect works really surprisingly well, and there are enough things in the water to keep it interesting. Somehow it really gives an 'up in the air' feeling, and using Pounder's birds was inspired..
It's
all sky. Tried to get as close as possible to the way the blue looks in the brief breaks between clouds as they stack up the day before a storm.
I was thinking that maybe it would look interesting to have two layers, a layer of grey clouds over the water/coast and a layer of white clouds over the top.
Maybe that would add even more depth as the grey clouds would look like another layer between the white clouds and the surface (water/land).
That's very good advice. I have the graphics as a lot of layers in a gimp file so there's a lot to experiment with. There's a greyer version of the heavy clouds for example. I'll certainly try out your idea. Your suggestion about depth prompts the idea of using low-opacity drop shadows where clouds are over the land tiles. Varying the offset & opacity would give the impression that clouds are at different heights. Same could be done where clouds are layered - added to your suggested technique would make it even more effective.
To solve your immediate problem: it might be easier to have No clouds over the coasts, save for a few rare whispy stragglers, and let the clouds start out on the OOO and SSS files. That might cure the "framing" problem. I'd keep the heavier clouds out over the ocean -even LM ocean - there's plenty of room on those files for larger, heavier shapes. Mainly, I'd try to keep it all light-looking, as it is now, because it looks like paradise.
One reason it's so busy was to try out a lot of different effects. Between the standard & lm files there's room for a lot of variation in the final version while keeping things low key.
Want to have just enough clouds & marine layer on the land tiles to get the floating effect. Mostly blue sky on the coastal tiles. Sea the wispier types of clouds - still lots of sky. LM Sea somewhat heavier. Ocean nearly all clouds.
In these early previews didn't even try to work on framing. I don't want to limit the clouds to the SSS & OOO files since that would make the land/coast clouding look weird. Making that sparse & building up as you get further from land will help. Thanks for clarifying that. WildWeazel's templates/guides include one for the WSO file which will help a lot with the framing. Adding the numbering from tom2050's templates to his files helps keep things straight.
Did this on Snoopy's terrain since a lot of Pounder's work looks like it's done with it. If something usable develops I'd like to make a Rhye's / Ares version as well. That's the terrain I use the most. The majority of the work should be transferable.
I love Pounder's birds & will definitely use them. It's really tricky getting the ones flying under the land to show enough to be identifiable yet clearly be underneath. I may have to steal frames from
this for an alternate version. Sometimes it doesn't matter as much what is posted as who wrote it. Thanks, Supa - if not for you and your work that idea would never have occurred to me.
