Hey dustinthetoucan here are some suggestions:
The theme of your template isn't generic enough to sell (if that's your intention, if its just for learning then have at it!). Try removing any specific elements that only work with that specific topic (the stripes, zebra wording).
Take a thorough look at some of the top sellers on themeforest.net. Look especially for layout, spacing, and how fonts are used.
The gradients are very contrasty which takes away from the appearence. Try making those much less intense.
Times New Roman is generally recognized as a generic boring font. It can be used well for sure, but try to stay away from it. Arial, Verdana, Lucida Sans, or Georgia are good choices.
Something worthwhile to do is find a great looking design, then try to replicate it (for your own learning, definitely don't try to resell it). Keep at it, the only way to improve is practice!
