'Having trouble positioning images in my Webpage using CSS

Could someone please take a look at my CSS Style Sheet and inform me where my mistake is? Anything I do to my img.otherimages selector, nothing happens and the image stays in the same position, on the bottom of the Webpage. Is there another selector I have that's dominating over this one?

body{
    zoom:0.8;
    width:800px;
    height: 600px;
}
h1 {
    margin: 50px 100px 10px 65px;
    color: #92CD00;
    font-size: 26px;
    text-align:center;
    width:380px;
}

.menubar{
    height:30px;
    padding:4px;
    border: 50px
    font-size: 18px;
    overflow:hidden;
    color: #ffffff;
    background: rgb(137,193,11);
    background: linear-gradient(180deg, rgba(137,193,11,1) 35%, rgba(108,155,47,1) 100%);
}
.menubar a {
    margin-left:0;
    float:left;
    display: inline;
    color: #ffffff;
    text-align: center;
    padding-left:10px;
    padding-right: 10px;
    text-decoration: none;

}
.menubar a:hover {
    background-color: #81b518;
    color: #ffffff;
}

p ,ol, div.paragraph{
    float:left;
    width: 50%;
    line-height:1.4;
    margin:10px;
    padding: 10px;
    display:block;
    text-align:justify;
    height:420px;
    font-family:Verdana,serif;
    color:#192402;
}

img.otherimages {
    object-position: right top;
    position:relative;
    right: 0;
    float:right;
    width: 50%;
    margin: 0 0 10px 10px;
    padding: 10px;
    height:420px;
}
img#leaf{
    position: absolute;
    top:-40px;
    height: 120px;
    font-size: 18px;
}
footer{
    clear:both;
    position:static;
    height: 30px;
    background-color: #81b518 ;
    text-align:center;
    display: flex;
    justify-content: center;
    font-size:18px;
    color:#ffffff;
    align-items: center;
}

Here's the HTML:

<!DOCTYPE html>
<html lang="mkd">
<head>
    <meta charset="UTF-8">
    <link rel="stylesheet" href="CssStyleSheet.css"/>

    <title>Најава</title>
</head>
<body>
<div class="menubar">
    <a href="index.html">Дома</a>
    <a href="servisi.html">Сервиси</a>
    <a href="zanas.html">За нас</a>
    <a href="kontakt.html">Контакт</a>
    <a href="najava.html">Најава</a>
    <img  id="leaf" src="Images/leaf.png" alt="leaf">
</div>
