In my portfolio there are 40 or 50 images that represent clip art on astronomy themes. Like these ones:
They are sold more or less succesfully and so, recently I decided to expand the collection. Today 3 new images have been approved (3 from 3). Here they are:
I plan to continue this work using PhotoSHop and very effective sets of plugins. Namely, FLAMING PEAR
which represends number of nice looking and easy-to-use filters and KNOLL LIGHT FACTORY
which helps to produce different kind of flashes, glares, blinks etc.
I hope such kind of images have considerably high selling potential.
