Tom,
I prefer the last two images from the first set. They remind me in colour
and style of detailed hand drawn interior perspective watercolour techniques
that existed before computers came.The bottom two of the last bunch seem
kind of over done with the brush strokes going in all directions. I think it
would be better to get rid of them. They seem to distract and take away all
the attention from the fine detail in the background.
By further postprocessing this image in photoshop for example by using
adjustment layers hue/saturation, curves etc. it is possible to further enhance
your original image without going into dramatic measures of using artistic
tools , brushes etc.
How much is too much, a difficult question, and I suppose we will never
have a general agreement on that one and that’s why we are here to help
each other out . I am asking myself through my work every day this question
and it is very difficult for one to judge his own work.
Cheers,
Mateo
