Some critique for you, given to help you to improve, not to nit-pick.
Think about the text size. You use large text which is very close together. I understand that's rather the style you've gone for, but it can cause issues.
On the split screen graphic, for example, The descender on the 'y' in 'Media City' could easily clash with the lower text if the 'y' lined up so that it appeared above a capital or a letter with an ascender, e.g. d, k, l, etc. Also, 'Media City, Salford' is quite a short location when split over two lines, however, this takes up 90% of the available space. What if the guest is in Southampton or Middlesbrough? You need to think of every possibility instead of putting a template text in and seeing that it works and leaving it be. Test the graphics you create out with different information, long, short, lots of ascenders, lots of descenders, numbers, letters with accents, symbols, etc to make sure that it looks good and works well whatever the text.
For what it's worth, I like the 'part-sun' logo and I think the shade of blue/green you've chosen is pleasing to the eye and suitable for a morning show.
Hope you find this helpful, Owen.
Guess who's big in the back time.
