you can see the back is not clean. too many wrinkles.
shoulder looks good though.
front also looks decent enough. however, i don't think the front is slim enough since you want that look.
the sleeves could be slimmer too and need to be fixed. too many wrinkles on the sleeves.
laslty, pant legs don't seem slim enough for a slim fit suit. you might have the legs taken in a bit.
hope this helps.
