I say go for it. I am still relatively new and have never tried a curve till a few weeks ago. I have two baby quilts I am working on that have curves. One is done and at my bros house the other is taking me longer because there has been much stress and sickness here. I found the curves challenging and not that bad. I have been quilting for about 3 years now. still new at it. I do like that quilt you found and with 10" blocks you should be good. just go slow and pin lots and take your time to enjoy it.
