Charlotte's Works

Charlotte- This is turning out beautifully. I think it still reads as a silver and blue color theme with the red accents just red enough to balance the overall look and fit the season.
The perspective on the vase and the pot is not quite right. I can't put my finger on the pot...might be lighting on the rim trim, but the vase is just the highlights on the lower fluting need to have more curve. Perhaps dropping the two middle highlights a tiny bit.
I see what you mean about the hyacinth...can you do a slight sharpening pass that would tighten up the edges? Definitely try it on a copy to see if you like it.
Ivy looks so real.

Beware!
Photoshop plugins may tweak the colours just as you want but will remove all information about paint depth and wetness and consistency. All colour mixing afterwards will be "different".

Here's a little demonstration of the filter problem.
I squeezed out a bit of paint from the tube and then used the palette knife before and after applying a Photoshop filter.



At point 1 you can see how a single stroke of the knife smears the thick paint easily and you can see the change in thickness. This is normal ArtRage behaviour.

At points 2 you can see how, after the filter, the canvas texture is now applied again over the paint where there was no texture before. This is because ArtRage so longer recognises it as "thick" paint.

At point 3, again after the filter, the knife now doesn't behave in the same way and you now have to smear back and forth to get any kind of blending effect.

Before the filter ArtRage understands the marks made by all the different tools and makes them behave accordingly. After the filter it just treats everything the same whether it's pencil, charcoal, thin paint, thick paint, and even the impasto highlights are just treated as "a different flat colour."
