Don't say you suck because you use templates! They're a tool just like our software programs, actions, styles, photo editors, etc. They're really helpful and fun to use, too!
Not every layout I make has clusters or flowers and I like to keep my style eclectic - I scrap however suits my mood at the moment. haha
When I do cluster, I tend to follow the odd-number of elements rule, too (greenery not included), and then repeat and adjust layers, etc. It makes the process quick. Other times, I just put everything I like in the kit on my layout and decide how to use it all. hahaha If the kit I'm using has some fun elements, I like to incorporate them, too. I usually just place them wherever I feel like it looks cute.
