Plant ideas for front garden

Hi everyone, 

I'm after a few suggestions on what we could add to our front garden. We planted mostly shrubs back in Feb 

Red robin

Hebes

Lavender

Heather's 

Buxus in pot. 

Ive picked up another small round buxus which I was going to put in a pot and move the lavender. I've got 2 other small pots but I'm not sure what to plant in them any suggestions? Would you add anything else? Or would it be best to wait and let the shrubs grow
