The join between Logo and DNA looks unclear and not regular.

in text, It may be greate to have the "Qt" world in green ? Same than header title bg ?

replace
" A lot of open source and commercial apps are build on top of Qt "
by
"It is an alternative to Java for builiding modern user interface and keep advantage of the power of C++"

@it-s correct if I spell wrong :D

You may want to add a footer or something else to display information ?

A small clue, logo or something else that identify your draw ?
All artist should put his mark somewhere ?

Would be better to keep only one footer . ( the white one or the dark one).
