Great. 
Keep up the good work!
For my own piece of advice, on the catalog page the way the image overlaps the products is distracting. If you adjusted your theme's CSS and added the following two things it should look a little nicer. 
img.category {
margin-bottom: 1em;
}
.category-grid-products {
clear: right;
}
