http://i.imgur.com/M3FqGiU.jpgThis one is really nice, good use of colours and I have the hots for serif fonts.
Not really digging the rest at all to be honest. Most of them look like low-budget company logos- I think mainly down to the font choice.
http://i.imgur.com/EFWPIx6.jpgThe logo itself here is odd because it's not consistent. You're using an S that has flat sides (like how an 8 is displayed on an LED screen), but then you're using an A with a pointy apex. In addition to this the curvature of the green line as it goes over the A does not match up with the other side, throwing off the balance of the logo.
http://i.imgur.com/1K2uoLr.jpgThis one is cool- a neat idea and not much more to say on it.
http://i.imgur.com/EChp79z.jpgPoor font choice and the kerning looks off, especially on the "supper club" text.
http://i.imgur.com/XZ78WZO.jpgI can see the effect you were going for here and it looks nice (I do like the football vector) but I think the gradient on the main text needs toning down a bit.
http://i.imgur.com/v9y0tGP.jpgI don't like this one. Nothing to do with you I just don't think it's a very good concept.
http://i.imgur.com/tNl6TdQ.jpgNot keen on the font choice here. I think the 4 stands out way too much. It's positioning throws off the composition of the rest of the letters.
http://i.imgur.com/f8s21fd.jpgYou should delete that font and never use it again.
http://i.imgur.com/RrqH5c6.jpgI dig this one. In my opinion it'd be better if the "i" was all blue instead of being a gradient. Grey-to-colour gradients don't work very well.
http://i.imgur.com/anCof7t.jpgNo comment. I'm going to assume the client loved it though :P
http://i.imgur.com/qSVi5T1.jpgAgain, I think the gradient on the "demand" should be dropped for a solid colour, keeping the one on the A-V. I don't like the underline and I think the slant on the first D should be further to the right, allowing for less of the curvature on the back of the D.
http://i.imgur.com/agLoF2c.jpgOnly complaint for this one is that I think the bolt in the middle should be a bit more prominent and have less jags. Would stand out a bit bolder that way.
Thought you might appreciate some proper criticism instead of these guys licking your butthole all the time. Good work, just update them font libraries man.
