Nice ambience in GirlTheme, though I my takeaway is that there wasn't much of an established melody to describe as a theme. Also, the popping sounds (almost sound like footsteps at some point?) in the background feel a bit out of place. If you were intending them as a texture in the song, I would have brought them more to the front of the mix.
Exploration - The pitch bends create some nice tension between the rest of the song, but the execution sounds a little rough, imo. Try steepening the curves on your pitch bends and adding some flatness in the middle. In most cases, they will sound better when they spend less time in subharmonic areas and more time on semitones. [think of a U instead of a V]
There are some interesting textures in HappyMemory, the synth doing arpeggios speaks to the title of the track well.
The sort of static background noise in SadMemory does a great job of creating that feeling of unease. Nice chord progression here as well.
Overall, nice work!
