I had to give it a go to Swansea City AFC .I liked the idea they had but I really didn't like the Swan and the Wordmark placement . My input was to make that "S" more prominent and clean and make the feathers a bit more wavy (sea/waves). At the end I added the boldness as I believed that it was necessary.
Note* THIS IS NOT AN OFFICIAL RE-BRAND OF SWANSEA CITY AFC!
