To the voyager & back

I put together my first hand lettered piece this past month in time for Valentine's Day. "To the voyager & back": a metaphor; a representation of distance, time and quantitative amount of love expressed from one person to another. Full size attached. (To be clear, the process by which I got to the result was via hand. This image is in fact a vectorized and printed version of the piece for copy purposes.) I know it's not perfect and I'm okay with imperfections, but hopefully it's a good starting point for me to only learn more and get better. Any and all feedback is welcome.
