Quality issues

[magdalena_2592]

Hi. I just started contributing to adobe stock. I'm completely new to this. I started creating digital graphics. I tried uploading a few images and only one was accepted. The others said there were quality issues. Can you explain where I made a mistake or give me some advice? I would be grateful for any advice.

You have asliasing in your assets when viewed at 100%. 

Aliasing are those stairs in the lines (edges). You should apply anti-aliasing to smothen the lines. See here: https://en.wikipedia.org/wiki/Anti-aliasing and here: https://en.wikipedia.org/wiki/Pixel_art#Techniques

In addition, I would submit PNG files with a transparent background, or even vector art for this type of drawings. That would greatly improve the market value of your assets.

I appreciate your answer. It will be invaluable to me in the future when creating new things. Thank you.

You're welcome.

BTW: the poor man's antialiasing algorithm is to design at a much higher size (2x or 4x the size required) and to downsample then to the taget size. You may need to experiment a bit with the downsizing options, so that the result is as required.
