hi guys, a newbie here just wanting to ask some questions and if possible to have it answered asap so i can get to work 
i was just wondering how do you make a subject/ person more realistic and not like being pasted on because i just cleaned out a background due to its wrinkles and just changed it to pure white but now the person looked like it's just dangling there outta nowhere.
#2) how do you add something to the background like the colored circles (ones similar to alvarado's style if you know what i mean)


, i would totally appreciate your help kind sir.
