here it is, please give feedback (and I prefer honest, even harsh critique, as its much easier to learn from that than from trying to discern the issue from a left handed compliment).
Again, right now I'm trying to nail down the geology of the map (plate tectonics and all that) so that is the primary concern. The other big concern would be am I close to 70% water?
So I just very quickly squished your continents together and slapped on some color to make it easier to see. I got this:
To me, if that is the entire map it appears to be about 60% water (maybe closer to 2/3 of the planet) ... nowhere near 80%.
That depends on several things. Climate is affected by the gasses in the air, distance between the planet and the sun, activity WITHIN the planet, etc. Currents will be affected by the same things... and by tectonic activity and by the distance/size of the moons.would the climate be similar (ocean currents and all that jazz).
Tons of things can affect climate so I couldn't tell from this :s
As for tectonics... I don't know much in that area, sorry
