Are you really this simple minded?
You asked why people weren't interested in your work.
I told you that is because you're doing what 90% of the people that think they are making good "photomanipulations" are doing, overusing stocks.
I also gave you a suggestion on how to change that and get more attention to your work, namely adding your own work to the stocks.
Want me to chew it out even more? You can add lines and geometric shapes for instance,
you can cut out pieces of the stock and place them somewhere else, maybe even rotated.
You can pick colours from the stock and draw a line with them.
Instead of taking that advice and trying to get better you tell me I miss the point of photomanipulations? That's daft.
Try reading it again and again if you want to get close to becoming a good graphic artist.
