Of course
I know you have worked hard, I want to say I do the same but your slightly better than me at game design, scratch that waaaaaayyyy better :) Out of interest when do you estimate the new levels to be out?
First click on File on the top left corner, click on build settings, a small windows should pop up. Then click on the button that says Player Settings on the bottom of that window. A new tab should appear in the inspector like this. 
Then press on SPLASH IMAGE
And the tab will expand.
Then press on the + sign, and add your own logo in, and that is it!
