Drawings of subject matter

I initially started off with the idea of using hands, however I think that having something that isn't particularly eye catching/interesting to look at will take away from the impact I wish the poster to have.
To avoid a boring looking poster, I want to include interesting colour combinations and several typefaces.

Though I am looking at a romantic theme, I want my poster to have something that every person can relate to. To achieve which, I will be using drawings of skeletons, as it's a symbol often used when wanting to portray equality and unity. I do feel however that anatomically correct skeletons may appear a little morbid and give off the wrong vibes and set about a negative impression.
To avoid this I have used the idea of making the skeletons look cute and a lot more child-friendly. I have used rounded simplified shapes and given them a heart.

To produce the illustrations I will be using the pen tool in Adobe Illustrator, as this allows for nice smooth line art and even colours.
