Your ISO and shutter speeds are too low. The settings for your images were 1/15s f/4 ISO100 and 1/20s f/3.5 ISO100. Continuous lights don't provide the burst of high speed light like a speedlite or a strobe, so you need a slower shutter speed to capture the ambient light (continuous lights are ambient light). Your 70D can easily handle an ISO setting of 800 which would give you 3 more stops of light. Normally for portraits, you'll want your shutter speed to be at least 1/60s to eliminate any movement (My personal preference is around 1/125s, but I don't shoot with continuous lights).
You could also increase your aperture setting to f/2.8 with your 100mm macro lens to get another stop of light. This would give you a little less DOF, but shouldn't be a problem for a portrait and you may like the result even more.
You might try starting with just one light which could give you results similar to the second image. Once you can reproduce images consistently, add the second light. Keep changing the distance between your light(s) and subject until you understand the results you'll get at varying distances. Also move the light(s) in a circle around your subject to see what type of shadows are created by the different positions. This can take quite a bit of time if you're doing self portraits, so you may want to practice with an object (perhaps a ball) just to see how the lights and shadows can change dependent upon distance and location in relation to your subject. Have fun with it. You're off to a good start.
BTW, just to show an example, this shot was taken with a single speedlite in a small portable softbox. This was just a quick setup because my daughter wanted a pic of her with her boyfriend.
This one was taken with a 7D, 17-55, at 55mm, 1/60s f/10 ISO250.
