Looking good! A few notes:

• Don't let images overlap with the logo.
• Move titles away from the corner, so they are farther in from the edges of the slide. Could probably stand to make them bold, as well.
• Overall type can get larger, but not necessary.
• When using images that run right to the edge of their white box, you could draw a white box, and place the image on that, so that the image pieces (like the blue outlined boxes) don't appear to be touching the edge.

Example of image that needs fixing:
