Good luck!

GREAT! Keep shooting! It's real pleasure when you see that people buy your photos

Congratulations and welcome to the community! I started only in August last year and got accepted at SS in November also from the first time but it took me some learning as to what to do and help from other members of the community. You should be proud of your achievement as you did it all by yourself and in a few days. I wish you all the best and I'm sure you will see lots of sales in future!

Even if someone does research before they start out, by reading here and the numerous "how to" blogs and websites, it ends up that step by step, you find the quirks of the agencies. I won't try to list them but the tiny logo Copyright issue is near the top of the list. 

Some day soon, you'll start to dabble with isolations, because they are one of the top ten selling types of Microstock. Soon you'll be carrying a camera and model releases with you everywhere. You'll drive down the road or walk someplace and say to yourself "hey that would make a nice stock photo."

After you get a nice selection up on the top seven sites, you'll start your day or end your night by looking at the sites to see if anything sold today. 

Next you'll get rejections for photos that you were sure were sharp enough or had good lighting, but one or two sites will refuse them and the other five will accept them. Added to that, they will sell at those sites, when the places that refused them also used "not suitable for stock" as a reason.

It's fun to watch and an interesting learning experience.
