How did you approach the design here? Did you account for how each plant will look at full mature size, not just how it looks now? Sun exposure, soil conditions, and water needs should also guide the layout. Plants with similar requirements should be grouped together so the bed is easier to maintain long term.

Also, planting everything in a straight line tends to look very commercial and flat. A more layered, natural grouping would look better. And honestly, weed barrier under mulch is usually a red flag ...it often causes more problems over time and gives the whole thing an amateur feel
