is 4-4-1-1 an effective formation??

[Nihal Manzoor]

i have changed my tactics from 4-3w-1-2 to 4-4-1-1 but im concerned that is this formation a good one to be used??
this is my team
orders down both flanks ,attcking,mixed passing,normal tackiling,zonal marking,no counter and no offside
should i change anything
