A very appealing piece of Typography I love the colors, the concept and the layout. The Chalkboard background and pink color go together very well and make this deviation very pleasant to look at.
Still i see some place for improvement. The heartshape, even if it's not a piece of typography is s a bit too simple in my opinion. Now i don't know how they were done technically but my tip would be to draw them as paths in illustrator and add some preset brush that will make them look more like drawn with chalk. To go into typographic detail, i would adjust the kerning between the letters and give them some more space, while reducing the kerning at the y's. That will give the type a more even look. I am not a big fan of so big drop shadows either, you could reduce their size and opacity and still get the effect without it being so distracting.
I tried to give you constructive criticism to help you make this already beautiful piece of art even better. It does look like a lot of critique, but i hope it will help you improve
