The textured background complements the elements but does not take away from them. The soft colors work well with a pastel pallet. The aqua and coral are a great pair and work well together.
The slight nautical/beachy touch is not overdone and kitchy.
It complements a casual event, but one that wants to stay slightly elevated with touches of traditional elements.
Slightly modern layout and wording, not too traditional and stuffy, but not ultra modern. A great design for your seaside event!
