Welp, I made this completely from scratch. It's for my Rainmeter suite, CUiRVE. The letters spell out 'CUIRVE,' from biggest to smallest and left to right. To see it in action with the rest of my suite, click that link up there.
The top of the E doesn't follow the curve of the serif of the I. It's a nice pic though. As for blurring, I see why you'd consider it but in my experience blur never achieves the desired effect. In this case you'd like to get rid of the saw-tooth edges but blur will only make them less sharp and wavy - not a smotth arc. How did you make this though? Because I can't imagine the pen tool giving you such rough edges.
Paint.NET is the program i used, first of all. I used the line/curved line tool and the info bar at the bottom for pixel-perfect placement. The E doesn't follow because I made it too high, compared to the bottom. There should be a gap the same width that the V made on the bottom as there is on the top. The jagged edges come from me turning anti-aliasing off for the line tool because it helps with the pixel-perfect placement.
OH yeah I lied. I also used the circle tool for the large circular sections, such as the c, u, the serif of the i, and the right side of the v.
