I created the illustration of Bob using an image from the internet as reference. Thought an asymmetric, cartoon like design would be appealing to all age groups in the target audience. Used the blue/black mostly, but included red to make the logo pop!
LuTeach....we like it. Maybe try a couple of different font/typeface style for the words.
Also...'WebTalk' we use as one word although that's I know different. Also capitalize the word 'With' also. We often use the verbage WTWB on the show and in commentary on it...thus caps are important.
If any way to add www.webtalkwithbob.com somehow without messing things up that too is good.
