Graphic is still too large. Visit the CPC site and download their templates. You're always best to start off with the constraints laid out. It sucks having to go back and resize, rearrange or delete elements of a great looking design to meet constraints.
Also, start with the largest denom in your set. This too will help in picking the correct font and size you want. Sometimes it's a compromise. But again. It sucks designing a great looking Inlay that works only to have to drastically scale down the largest denoms.
