Overall your project was executed perfectly. I really have to nick-pick to find any serious errors in your charts. The final chart labelled "Returns by Category" has a potential mistake. For color blinded individuals you have to avoid using certain colors in comparisons as those who are color blind won't be able to distinguish them. Red and green happen to be one of those color combinations. Changing the green to blue would have been a better mix.  Also you line chart labelled "Sales Over Time by Furniture Sub-Category" has two lines as different shades of green. Considering the fact that there's only four variables being charted on this graph the use of a different color would have been better to have greater contrast. Looking at your numbers, I really can't tell anything out of the ordinary. The information flows well between charts, and is consistent which is important. 

The bar chart "Sales by Sub-Category "Office Supplies"" had all the correct information with perfect contrast.; anyone could read it. The axis and label were correct by the order of the individual bar is strange. Having the bars in a ascending or descending order would aid in being able to read it. Having the bars mixed up results in greater difficultly understanding the chart.
