<p>Ok, so last year I learned its ok to break a few grammar rules to create style (like do some fragments). Is it ok with essays? I'm really used to doing some of these things to create voice in my essay so I hope its alright.</p>
<p>As long as it's not too colloquial/informal, you should be fine, but it really depends on how you are breaking the rules/what rules you are breaking. Developing your own voice is great, but it still needs to be understandable</p>
