Just listen to the fucking experts and watch the godamn tutorials before you get cockslaped! Your graphic skills suck, no no excuses you must practice and learn to be good at it and thats, that no short cuts!
This is my first photoshop creation, please let me know in PM what you think, pros and cons, how It could be improved and things of that manner. Or skype gsjackson413
Soo I see you have just found out what the overlay,screen and soft light do. Tutorials maybe a good way around ,but to really get into it just start testing out , play with opacity , transformation , image sizes... just taking the pictures and mashing them up wont do any good. I can tell you on the second one you could just make the original of the man smaller that adding it , bend the levels a little so it gets a nice mood , play with the saturation , contrast .... (easy stuff ...) GL
