My teeth look like above 2 picture.. Do u think I should go for teeth braces..?

i put a brace on this week which is 26 year old for me , the doctor extract 4 teeth and because my ages and my teeth structure is Even -.- , the doctor say if the teeth structure is uneven , the result will be more fast  and mine require longer time so i need wear the brace at least 2.5 year .... about the cost first payment is RM 1k include teeth extraction and first year month payment is RM 200 , and start from second year is RM 150 monthly until the end .
