Having fun with improvisational piecing

Quite shamelessly using this stunning quilt as inspiration I've currently got another baby quilt in the works - I started improv piecing some of the blocks last night, so far I have four (not cut neatly to size yet, but you can get the idea):

I'm now second guessing my fabric choices though - I'm pondering whether I need another dark pink (like in the pink stripes). What do you think?

It's quite fun just making it up as I go along, hopefully the quilt will turn out alright with me doing it that way though! I'm planning on doing something similar with the jelly rolls so it's good that I enjoy it.
