Thanks everyone for the feedback!
Let me break this down:
Does it submerge when moving/loaded? That would be even more awesome...
Yes it does, it stays submerged with only the tower/bridge/whatever-it-is sticking out of the water, and only surfaces for loading.
Is it possible however to have different graphics when it moves through rivers? It would be cool if it is half submerged in rivers and not fully submerged as rivers are not as deep as oceans.
Should be possible, yes. However, I've set the speed on canals/rivers to be very slow, since it isn't really a practical river boat
It would also look weird that it can travel up a lock submerged, but then pop up on the canal (unless there's a way to check for locks as well?). I'll have to think about this one.
I would make the submarine bit more in water... if You understand what I mean. At the moment the submarine lower side is dark in / view that means its lower roundish shape is seen, but normally it isn't so (see picture). I would leave the end as is but make it bit taller and lower it into water two or 3 pixels or recolor so that it looks like on the picture.
Yes, I guess it can look like it's sitting on top of the water in some views, but it actually isn't drawn that way. I don't know what you mean by making the end taller, though. Do you mean front or back?. Right now the sub is meant to be about 50% in the water, so not the whole tail fin area is exposed. As for the rest, getting a cylindrical shape (or half cylinder, I guess) to look right is somewhat difficult, and I didn't want the sub to be too bright, so I used some darker colors near the water line to accentuate the curve. Keep in mind the 'sun' is coming from up high, and I need a little contrast for shaping (otherwise it will look flat). I might touch up spots in a couple of views (like the one in the screenshot, now that I look at it), but I think mostly it is fine. More input on this would be helpful though
Good work on ferries, and for the submarine, if you're really motivated, and you like challenges, you could try to do the great transatlantic, not necessarily to their actual size, but even if there are a certain scale is already well ...
It would be nice to see transatlantic as Normandy, the Titanic ...
That would certainly be a challenge, but sounds like something for another project. I've thought about broadening the scope of this set a little bit to include things like maybe a couple of cruise ships or a coastguard ship, but that's as far as I would take it
At some point this GRF will probably become "Ships of Puget Sound" rather than just "WSF Ferry Set", especially since I've already gone outside the bounds of its namesake
That said though, I'm going to try to focus on ferries first before I wander off again on something random
Hopefully next I'll work on something 1800's, either that or try the Kalakala again.
Same goes for the warships, not really my thing, plus it sounds like a whole other game
Maybe someone needs to make a 'unique ship set'?
