I think they'd be awesome if you used the fonts/images of the original logo's but that's just my opinion. the angles and editing are awesome, especially on the canyon banner Maybe stadium could use some more action.
edit: or no logo's at all I'm sure you can come up with sth
I think Tuta's Canyon one's angle looks a bit weird.. somehow stretched a little to much. but that's my opinion ^^
The stadium one is really awesome tho
