[themes] Workflow Question

[Tony Crockford]

I'm new to Drupal Theming, but have solid experience in PSD to HTML/ 
CSS  template creation, in other words I can build the HTML and CSS  
for a visual, efficiently and quickly.

So my question is is it easier to adapt the Zen theme to a visual  
design, or is it easier to convert a set of HTML and CSS to a Drupal  
theme?

or am I asking the wrong question?


What do you do?

TIA
