Yeah, fist work on your photography. It needs a giant overhaul. I looked at some, and I was like, "Is that laundry in the background?!" If you don't have space, get white cardboard, and use that as a backdrop to make it less cluttered and more proffessional.
And you'll want to use more than just one picture.
And join an SEO team and work on that.
Also, for this item, you have a drop down box for us to choose what color we want, than in your description you say this is for any design we want, but the item title is for a patriots beer glass. You'll have to make up your mind what this item is going to be. If its going to be a Patriots glass, why the need for the choice of colors? If its going to be a custom design, you might want to have a logo saying, "Custom Design of your choice" picture, and change the title to reflect that.
