You have a beautiful (bonito) website and your artifacts are just wonderful. It would be sheer joy to write the copy for you (well, that plus my bid).
I'm a musician and love Latin music, so I was immediately attracted to the instruments. Now I'm worried I'll spend what I earn on an instrument.
You didn't specify wordcount. The text you currently have on the side of the graphic matches the height of the graphic, so I'm not sure if you have a space constraint requirement.
I'd like to write something with more text than what you currently have. This could be a mention of many of the categories with a short but catchy phrase; and a chance to mention a handful of specific items, i.e. the tongue drum, the "Fisher" (oil on canvas), the "Twins" pillows, etc.
The copy will remain tight, but ultimately a blend of the Mi Arte Es Su Arte philosophy mixed with the categories and specific artwork.
The artwork is truly beautiful and I say that whether I get the job or not.
I've never actually written radio copy but have had plans to write jingles (I'm a songwriter and freelancer). My primary area of focus as a freelancer is entertainment, mainly music and film. So I'm well-tuned to radio/TV ads.
