hi tinybird - i was ill for a while, so i couldn't go on with work and i didn't answer. sorry. now i am back again...
thanks for advice - i tried some of your suggestions:
format boy middle: first i changed the format to change the look of the book. i think it now looks more clean with seperating text and picture on each page. that fixes the problem with the boy overlapping in the middle. i changed the composition a bit and moved him to the right.
color/ nightfeeling: i tried to change the palette (pic02) and added a filter on (03+04) to make it more look like night. i think i have to choose the "effect layer filter-method" to add light or shadow to change colors. because i am really struggling with color palette, because i don't have much knowledge in color theory.
