The two bottom layouts are most interesting. This is where you were allowed to use more size and weight change. A word of caution…..when making some letters bolder thanothers a checker board effect can result and distract from the messsag of the word(s). Using different colors in this way is also difficult to use successfully…until you have more experience.
	At full size, the bottom left layout paragraph does work well with the different point sizes and weights. Making the column width narrower would add to the layout. …nice job!
