Tin Tin - you can always place the new elements at a smaller scale if you like. We do have about 3 more prompts coming with about 4 per prompt. I did give you all the "larger" elements first thinking they would need to be laid down first, so hopefully this will work out for you all.
I'm a rookie at this too - so I'm crossing my fingers it all comes out in the wash! So far, it's definitely looking like it. I'm loving what I'm seeing!
