Wow, looks great. I like the layered edge effect too. Real nice water color effect.

This is really neat, I especially like the smoothness and the vibrant color. Please share your steps, Thank you

Great job and great truck! Did you use a blur layer set to darken to get the finer black shadow lines at the beginning? Looks a lot like that effect that I get from KPT gaussian blur, which does the same thing automatically. Love the color...yellow with rust...wow. Was it that color on the original? Please share the original so we can appreciate and understand better how you treated this pic. Thanks.

The basic steps are under Sarahs Watercolor Tutorial.

Everyone is different and i might occassionally slip in another filter of some kind. This one had a layer of Photobrush's Oscars finest Watercolor. Other than that just the smart blur normal and median. Much of the effect comes from your choice of brush and opacity and layers of it when painting it back in.

Great image, Sarah. The results of your watercolor technique are simply gorgeous.

Here's the output from my "Tiger sketch" action.
