You said that you could make something better than a £400,000 costing logo design. Without looking at the design, one would think that you were boasting your capability of being worthing of pay. People that receive pay for their service are usually able to give it to a high-quality.Depends what the signatures for, in that case, thats what they requested, and they were gamers, so the signatures are relevant to what they wanted. I didnt boast how good i was, i never actually mentioned i was good , i simply said its a piece of crap and even i can make something better than that.
Also, i didn't say that your designs weren't relevant. I said that they weren't logos, as they are. They are graphics. A logo can be hand drawn, whilst a graphic is done on a computer with a software package, like PS or Coral.
