Rolf, I agree that your 2nd attempt is better than the first, so you're getting there.
However, as Dave B pointed out, you need to draw the scrolls without kinks, dog legs or straight parts. I know it's difficult to draw a perfect scroll, but for the carving to look good, it needs to be pretty close.
I don't know how you are laying out your design, but to start, I'd suggest drawing it as a single line for each side of your design (above the tang and below the tang in your picture), as it's easier for the eye to pick out straight parts of a single line scroll, or areas with a kink or dog leg.
After you've perfected the single line drawing, use it for the center line of your carving design, and add whatever width you need for the carved elements to either side of the single line.
If you have one of those clear plastic French curve templets, it might help you with smooth flowing lines.
Keep at it!
John
