A very cute character design! Perspective can be daunting at first but I will try to help. I see that you did draw in a horizon line and vanishing point which is good! But since you want to see the sides of characters or objects, that means there should be at least 2 vanishing points which I don't think you added. Both vanishing points should be on the same horizon line and can be any distance apart, even far off the page! To figure out how to follow a vanishing point that is off the page you'll want to use the brewer method! There are video tutorials on youtube that will give you a demonstration of how to do it so I won't go into it here. For now I'll give you some general perspective tips that confuse a lot of beginners. First is that you can have as many vanishing points as you want! Each object or character can have their on vanishing points! Even different parts of the same body can have different vanishing points than each other. This is because different parts of the body can be angled in different directions from each other. When you turn your head, you're changing the angle of it, which means that its vanishing points will move somewhere else on the horizon line. But turning your head doesn't turn your ribcage or pelvis, so those things now have different vanishing points than your turned head. It's the same as if you were to turn your pelvis in a different direction to your ribcage. Try drawing 3 cubes at different angles in perspective. You'll see how they don't share the same vanishing points as each other. In this drawing, the floor and bookshelf are in a different angle than the characters are, so they have different vanishing points. Another important thing to keep in mind is that the further BELOW the horizon line you are, the more of the TOP planes of an object will be visible The further ABOVE the horizon line the more of the BOTTOM planes of objects will be visible. When the horizon line is really high or super low, this is when we'll begin to see foreshortening and objects or body parts that are stacked on eachother will begin to overlap. This is why being able to break down your characters into primitive forms like boxes is important! It's much easier draw a box in perspective than it is to draw a character in perspective. Once you get the hang of stacking boxes and cylinders in perspective, characters become much easier. I hope this helps!
