Hello,
our latest submission to themeforest was rejected for following reasons :
"Theme does have a potential, but it is too generic and usability is pretty poor. Also, animations are very distracting and all over the place."
please guide, how usability can be further enhanced [DEMO][1]
You can improve the hover effect on buttons and remove any unnecessary animations on the page. Also you may want to increase the left-right paddings on some buttons. This should make them look better.
To much animation … use it for fading in from just a few pixels above the requisite position rather than completely from corners.
Typography is a bit weak revise it.
The cart and search can be replaced for a better version to correspond to your style.
