I have to agree with the rest of the people, but I think that if you are not really happy with it, you have the right to tell them. Don't be shy, just let them know that you were expecting something a little more professional. I think it looks good, but is pretty basic.
nice looking logo.. but 50 bucks is a bit much.. there are guys on this forum that do things like that for 5 - 10 bucks
$50? How many hours do you think it took to make the banner? That would have taken me 15 minutes max.... Did you visit the person's portfolio before hiring them? (might have been decieving!)
I think $50 is a bit steep though considering it's just text on a stock image. If the designer took that picture him or herself then $50 is not a bad price but otherwise I think I think it should have been much less. It's not a bad looking banner though.
When buying anything artistic the going rate is what the market will pay - I mean I wouldn't pay jack shit for the mona lisa where others say its priceless. Beauty is in the eye of the beholder. I know someone else who designs banners for $40 so you are paying at the high end of the market for banners - but consider designers for most business logo's can charge 10's of thousands.
