Very impressive results. I think the water looks truly great. What stands out to me (but I hasten to add that I say this not having seen the photograph and, even more importantly, not knowing how you want the painting to look) is that the sky jars a tiny bit with the smooth tree line and the beautifully rendered dynamic water. The central part of the sky is very dominant and pulls the eyes in. Skies tend to do that, especially when there's a G class star in frame
but here I am wondering if, given that that's how the viewer's eye will react upon viewing the image, you want the sky to look like a sort of 'splash' or if you'd like to smoothen it out somehow to match sky's beautiful reflection in the water which is considerably less bright and energetically shaped? In the same vein, the highlights in the upper right-hand corner also seem a bit too bright and "blown" when compared with the water's reflection thereof.
I do like the play with the depth of field in the imate. Focus seems to be placed quite close to where the viewer stands, probably somewhere in the middle of the water, which is how a landscape photographer would do it to get as much DOF as possible throughout the image. Here, though, the photographer appears to have used a very small aperture, probably combined with a (graduated) ND filter to limit the DOF to the foreground of the image (and ensure that detail remains in the sky since a longer shutter speed would have been necessary to illuminate the dark foreground). The tell-tale sign is that the tree line is out of focus. The sky however appears to be less out of focus than the tree line (the splash is quite defined), which photographically speaking is an optical impossibility and jars a little with the rest of the image. A simple solution would be to add a small degree of sharpness to the trees' outline or to blur the sky ever so slightly.
I accept that not many viewers would probably notice this, and also that this is a painting of a photograph which opens the field for all sorts of artistic interpretation which is not available in-camera to a photographer. So whether these things matter at all depends on your artistic vision and I'm therefore hesitant to say this and hope you don't take it as criticism. It is a terrific image as it stands

I have spent the last several weeks composing the following painting based out of a photograph in Photoshop CS2 on my MDD and G5 for a special occasion.

I think it's alright. However, I am still not 100% on the water's color fragmentation.
