Art I would like to collect

I have a small collection of artwork, some pieces made by artist friends, some bought at various street fairs or shows (and some of my own work as well). I would like to expand my collection, and there are a few artists whose work I've seen online that I would love to purchase from. Here's a few of my favorites:

• Mike Libby's Insects
  I like the spiders, cicadas, and beetles.
• Lockwasher Design
  Beautiful retro robots and rayguns made of recycled parts.
• Audrey Kawasaki's Paintings
  I really like the one with the octopus arms.
• El Rey
  I've bought work from El Rey before, but never for myself. His krylographs are pretty cool.
  
• James Jean
  I came to Jean through his work on the covers for the Fables series. His Recess prints are quite striking.
