I have absolutely no good taste in font but... Id say go with a simple font such as Arial and blend it in.
No, you've got the whole idea wrong. Splash images are supposed to to be very simple and normally are text based, not brushed over with renders like signatures it looks good though, not for a site splash image, but still good, I would change the font color though
I have thinking of switching the fonts, coloring will be hard to change. That electric blue is almost perfect for its purpose I believe. I may have to change the tables around.
