At the sign of the dot bomb as a strap line only works if there is a bomb replacing the letter o in com. Without this (your design doesn't include a bomb) the strap line does not make sense. I am happy to drop the bomb (corny pun wholly intended!) but if so the strap line must go as well.
If a figure is going to be included it needs to be more in keeping with the fantasy nature of the games, probably something orcy (or orky) looking. Warhammer 40,000 is the most popular game in the range so an image that relates to that would work well. The figure in this design is too generic.
