I don't have any gym equipment at home nor can I afford to buy them. I would grateful if you can suggest me some improvements to the routine I have made or even better if you could suggest me a better one.

Hi, don't know your name yet,

First of all, congratulation for seriously deciding to go for better health and fitness because I have seen many of your age and friends deciding and making all those plans but eventually gives up because bodybuilding (even amateur) requires a good amount of dedication and devotion. Bodybuilding is something which you are doing even when you are sleeping because it needs your control on everything, your sleep, your food, your habits, your daily routine and so on (ofcourse with proper exercise).

Now, keeping it short.. you need a routine which is effective without Gym and Equipment.. so, answer is Calisthenics, or bodyweight exercises, originated thousands of years ago in ancient Greece and have been a major component of fitness in athletics, military, law enforcement, and daily fitness for home workouts without equipment.

But before all that, you need to have decide your goal, ofcourse you need fit body but what do you want to be in next 12-16 weeks ?
1. Bigger
2. Leaner
3. More endurance and stamina
4. Bulky - Heavy and so on..

So, there could be many more things, here making your schedule depends your body type, previous experience of exercise etc also.

Btw, from personal experience, I can tell you if you know how to exercise properly, you can make very good physic with Calisthenics only.
