Ok feedback for all,
1) The font is great, the .co.uk is a nice size, but the logo would be expensive to print as there's a gradient involved. Also I'm not overly keen on the logo.
2) Again, font is good. I'd make the .co.uk the same as #1. The logo is a little bland, but would be perfect for print.
3) The text looks mismatched in size and leading. the Logo is too big, and it isn't so obvious the first word is 'working' and there's a gradient so lots of colours to print.
4) main font is good, but the .co.uk looks tacked on because of the stretch of the font. The tie-i logo is good, but imo a little big.
5) Not a fan of the all-caps type, and the logo looks odd to me. I'm not sure what three people who have had their arms amputated standing with their legs wide open have to do with working?
6) Same as #2 really, looks nice, works well for print, just a little bland on the logo front.
