is it true that you're adding dark brown diffused edges along the panel seams, the bow& stern are sort of brownish and a littl blunt and that you're actually a fairly slippery charactar and that you're adding hatches that are flush on the cockpit side but the hatch panels sort of curl up exposed towards the ends, and that the hatch gasket that you can see is sort of off white, and all your drybags are off white??

and anyone paddling it has unexpected compulsions to roll over??

(in truth, in might be very interesting (and yet still as visible) to lightly airbrush the panel edges w/ a slight contrast, even a low contrast off white)

sounds like you are really close! good luck.
