The logo itself looks a little dated to be honest. I think we're past the stage of glossy logos and overly vibrant colours used in combination. The colours work well together, but I wouldn't split the colours of the tag line, keep it the same.
I'm surprised that you've chosen to use the word bee and haven't incorporated that into any of your branding! It seems like a bit of a no brainer to me, and I'm quite confident you could get something good to symbolise graphic design and bee.
I believe the kerning is a little off for a few of the characters in Graphic Bee.
