.5/10
the only photoshop I can see is the text, and text stroke. The rest you obviously copy and pasted. The background looks (and probably is) a small picture that you resized to fit these dimensions, so it is extremely pixelated.
The renders (if those are considered renders) are terrible cuts. They are also way too small and low quality for that sig size.
Quote... it is hard to read the words "the future" and "has nothing". The light from that window obscures it. Try blending options here, as it will flow with the sig instead of the whole thing one color.
Title... No. Font doesn't match the theme. The stroke just makes it more illegible. I can't tell you how to fix it, just completely change it.
How to make it better...
Make your own BG, don't copy and paste it.
Text
Render
In Google just add the word 'photoshop' and then add stuff like "text" "effects" "lighting" "backgrounds" etc.
