Well, I did my humble picture contribution here on Dreamstime.
300 pictures is not that bad I presume, but it's far from my final goal.
Considering lack of equipment and my experience in this field I can't be totally unsatisfied.
Hopefully my next 100 pics online will appear much sooner.
About sales... well, it increases each month by a little, but it's fun to "climb" on a curve of success.
Keep your lenses always clean...
