1 lb a week is a very realistic goal, and 1.5 lbs is certainly do-able, but at that rate you need to ensure everything's in check.
Do you know your estimated lean body weight? How much protein are you consuming? How much fat? You said carbs were higher than fat. I'd switch that up. Lower the carbs, and cycle them between non-training and training days (i.e. carb cycling diet).
For instance, on non-training days make your only carbs come from veges. Even a large amount probably won't bring you any higher than 50g or so. Make sure to consume plenty of leafy greens. Brocolli is great when cutting. On training days eat the same thing but add a grain source, ideally for pre-workout. You don't want to add to much, but enough to (a) fuel your workout and (b) balance out the calorie deficit, as it will drop on training days due to calories burned. I perform cardio after my workouts on the "low carb" days, so I add about 300 calories, 60g carbs worth of grains in my pre-workout meal. Something like a large bagel, or 300-330g potatoes (some types are more carb dense), or 85g whole wheat pasta, etc.
Then, once every 5-7 days (which is a good amount of time if you're running daily calorie deficits of 500-750 calories) have refeeds. These are days where you consume a calorie surplus, with an emphasis on carbs to increase leptin levels in your body (leptin is a hormone that tells the body it's receiving adequate calories...it drops when you diet, and so refeeds are intended to prevent your leptin from dropping too low, which would cause your metabolism to slow down, and cease fat burning). Leptin responds best to carbs. Keep your protein the same, ideally drop the fats to a suggested 50g or less, and consume the rest in carbs. A 500 calorie surplus is probably good enough. However, don't be tempted to binge on crap. This isn't exactly a "cheat meal" day, as refeeds are actually intended to ensure your cut's longevity. The more efficient your refeed the longer and more efficient you can continue burning fat.
