What I'm doing wrong?

Do not buy paid spots. If you buy anything buy some submit passes. Lots of guys offer monthly submit accounts for $20-$50 a month and it allows you to submit 1+ galleries a day. Not guaranteed listings but with those galleries you should get listed often. Submit passes can be found at various sites including gallerytrafficservice.com.

Your galleries are ok, the last one is the nicest layout I think.

Problem is this. You need traffic to make sales. You are new so most sites will not list you. Too many submits now so they cannot take on new submitters. That is why you need to buy passes if you are serious about submitting. Buy passes from teen and general tgps based on your submits.

One last thing. Over time traffic from tgps can be very protible but you have to mix it up. You cannot stay with the same sponsors over and over again, you need to try out new ones or at least new sites from the sponsors you use.
