Everything you need to make a good meaningful sentence (and grammatically correct, of course), is to follow common rules. Do not forget to provide your sentence with complexity, but you don't have to make them too complicated, I mean you need to use key words, they will make your thought completed. And the second point is that you need to properly organize the sentence using correct word order. ion:
The painter uses bright colors to give particular life and extravagance to the piece. additionally, the woman in the photo is centered in the middle of the frame and takes up a majority of the photo. because of this, it is clear the painting revolves around her and she is very important. lastly, since there is not much in the background of the piece, this further emphasizes the fact that the woman is the key feature of this piece of art.
happy arting! :)
