Finally got around to taking a boo at your thread, and great stuff you have posted so far!
First fave is the "you're welcome" banner, I really like the white/almost cloudy/ish kind of effect you have on it, very beautiful, and the blending is really well done as well.
Second fave is definitely the Dawn/Connor piece. Not only do I think they would make a pretty cute couple, but there are a lot of up points to the banner. First, the expression on their faces are somewhat similar (one isn't smiling while the other is scowling) and they both have a somewhat fogged look, which does a good job of reinforcing your caption (pictures match- characters match). And although you can tell they are two separate pictures, the lighting in them is similar enough that it works nicely, and it's pretty centered. To top it off, I'm in love with the border! So pretty! 😀
My third (and final, although these are in no order other than date 😉) is the running away wallpaper. Again, you did a good job of using pictures that reinforce your caption, as in them Buffy is alone in the type of place that we often associate with freedom (which ties in with running away somehow, at least in my brain it does). The textures/colours on the background is nice too, and although it's simple it is really pretty.
So great work hun! You have some good stuff here, keep it up! 🙂
