For that price point, this should sell like hot cakes.
A few suggestions:
The cursive writing at the back does NOT look nice, consider replacing with your MK logo instead.
Green & Yellow appear to be missing, these are quite a popular colour options
If you want to increase interest (And demand), opt for non standard colours. Examples: blueish green (Refer to Tind's Ultramarine), anodized bronze, anodized copper, dark charcoal, etc.
