I haven't got around to saying anything yet, so here are some
thoughts on each concept:
1) I like this one, although I'm not convinced by the font or the
lack of accents.
2) Seems quite dull.
3) Looks very like an old Intel logo (rotated 90º anticlockwise).
Also looks quite like the Alliance and Lester logo.
4) Better than 2 (I like the accents), but still quite dull.
5) As others have said, this reminds me too much of Nestlé.
6) This one looks very Uncle Sam.
7) I don't like the flower in this as much as the one in 1, but I do
like the font better. I think making the initial é lower case is a
bad idea, since (in my brain at least) the symmetrical és are removed
and I just see the `toil' in the middle. Not ideal.
The flower from 1 with the font from 7 and the first É capitalised
would be my favourite. I understand that the flower was simplified,
but even the original is not that complex, and is quite recognisable.
