Will I lose weight or gain muscle on this exercise plan?

I lift weights for 45-60 min 3 days a week. On rest days, I do 10 min of ab exercises and 20 min on the elliptical. I eat between 1500-1600 calories a day and 60-70 g of protein daily. I also try to walk for at least an hour everyday. Will I gain any muscle, lose weight, or just maintain if I continue?

I'm currently 5'4 and weigh 115-120 pounds
