Create an image of a powerful Viking warrior. The Viking is wearing a bear's head as a helmet, with the bear's fur draped over his shoulders. In his right hand, he is holding Thor's hammer (Mjölnir), which is surrounded by subtle lightning bolts. On the hammer, include a faint outline of the HSV (Hamburg football club) diamond emblem, subtly integrated into the design. The overall style should be bold and epic, capturing the strength and mythic qualities of the Viking and the symbols. tattoo idea
