You have a typo in the description, different.

There is a partial blue outline visible in these images.
It looks as if you have attempted to change the color on an older set of icons.

This set is not eligible for entry in the TOTM Contest as it is a recoloring of a previously uploaded set.

Only new work will be accepted. Please see the contest rules - http://www.rw-designer.com/entry/1415.

1.5 out of 5 stars.

I agree with cdl. You recolored this set and made it look like it is new work, which it isn't. Try to make smoother images by using a vector layer. Try harder next time.
