Personally, I hate looking for ends to snip after the quilt is quilted so I would follow the flower outline, do three or four tiny stitches in the same place, move to your next flower. Put your needle down in place, do a few stitches close together, pull up on the threads between the two flowers, so the bobbin thread loop is visible (you need to do one first, then the other, you don't want to pull too hard) THEN you can cut the threads from flower one AND the new ends from flower two. It's a lot of stop and start, but you will be SO glad you did once it's all quilted and all you have left to do is sew on the binding!
Honestly, though, there is no right or wrong way. It's whatever feels comfortable for you.
Be sure to post it once it's done!
