The logo will appear on merchandise (t-shirts, hoodies) as a small crest over the left side of the chest. If the lineart is too thin/elegant, it will not be very visible.
If you wish to add a colour other than black/white, please bear in mind that any colour not bordered by black/white will affect the colour shirt I can print the logo on. For example, if you choose red as an accent colour, then it may not show well on a red shirt.
I would also favor something with more vertical dimensions. Going too wide might not suit the space.
In terms of font, please feel free to experiment - but as an example - I am partial to the capitalised, worn look of the "Ringbearer" font.
Please also feel free to explore other sword designs than the standard straight sword. For example, greatswords like the Zweihander and Flamberge also have attractive designs.
NOTE: The brief deviated away from "Broken Sword" as a result of collaboration with the winning artist. Said artist originally provided a winning Broken Sword design as well.
