Second one is more successful than the first.
The composition of the first one is disjointed in two significant ways. The most glaring issue is the blob you have between the two images of Sansa. It separates the focal point and disrupts the flow of the piece. Having them touch much like you have the second piece would have created for a more pleasing composition and flow. Secondly the hard edge you have on the left image is a further disruption and divides the image in a way that does not feel natural. It goes: black space, Sansa, smear, Sansa, reddish space. It doesn't feel composed and unified. Each element doesn't blend into the next. It's possible to take something less orderly and more fragmented and make it work, but I don't think that result was achieved there.
These problems do not exist in the second piece, which feels much more complete and solidified. The pieces fall together in a way that looks right and there are no subdivisions in the image that feel disruptive. The only real criticism I would have is that the blending on his hand and the hilt could have been smoother. Regardless it shows that you're moving in the right direction with this sort of composition. I know you've been working at it.
Keep it up.
