I poured a third layer of resin onto the Kabul River board and “agitated” it to give the surface some current.  Overall I think it turned out pretty good.  To be totally honest I think I added a little too much color tint to the resin, resulting in a more solid as opposed to somewhat translucent finish, but the color itself is okay and I’m very happy with the “current” resulting from me dragging a popsicle stick through it late in the curing process.  The current I ended up with on the pair of Logar River boards is not as active.
Anyway, herre’s a few pics…

Next I added a third layer of resin to the Khairabad Swamp board, which had only received clear pours until now.  I’m pretty happy with the color tint here also.  I considered slightly “agitating” the larger areas of open water within the basin but in the end decided it would be better to leave the entire swamp perfectly still, since pretty much all the swamp water I’ve ever seen in my life looks that way…

Now I am faced with a perpelexing question: am I done…?
On the one hand, the 4 River and Swamp boards all look pretty good.
On the other hand, I’d prefer for the color tint to be slightly lighter (adding a bit more yellow ochre ink to the mix should get me that result) and I’d like the two Logar River boards to have more “agitated” current visible (I stopped dragging my popsicle through them probably 15 minutes to half-an-hour too soon, allowing them to cure with only slightly uneven surfaces), and lastly… there are a couple of slight imperfections on the Logar River boards — one little spot on the river surface and some slight shortfalls at the edges where they are meant to seamlessly join with other River boards.  These are not horribly bad but I think they are fixable.  However, if I try to fix without adding a full-blown additional layer of resin but just adding a tiny amount of resin to the spots in question, I may end up causing more harm than good, depending on how closely the color tint matches what’s already there.
Anyhow, after more than a year of work getting to this point, I confess the answer to this question of how best to now proceed is eluding me, at least for the moment!
I’m thinking about possibly moving my desk and setting the full layout up again, to see how it looks with the “water-boards” in their current state.  I have a feeling it will look pretty good, but course as always the devil will be in the details. The down-side of doing this will be having to change my office from “workshop” mode to “gaming table” mode, and then — if it turns out I still need to pour more resin (which is very possible) — change it back again. All of which requires more time and effort.
One way or another I’ll figure it out and if I do set up the full table again I will definitely take a bunch of pics and post them here.
I guess all I can say now is STAY TUNED!!! (and to all those readers of this blog who have been leaving comments on these seemingly endless river-related posts, THANKS VERY MUCH for the support!!!)
