As someone very new you would be better seeking out other posts (such as this one) and commenting on them. Your comments need to be valid and relevant to the topic though. 

I can see you are a model and have already done your intro posts. Everyone has something to offer, and your dTube posts may not be the best thing to start with. 

Tell readers about what you are doing, how your day was, it doesn't need to be too serious, just factual. Be a journalist, if you see something out of the ordinary take some pictures with your phone and the write about it with a personal opinion.
