I love the piano one, especially the start. The start actually reminds me of Albion's older music and Crystal Towers 2 main/ending theme (
http://albion.bandcamp.com/track/ending-tale-of-the-cave ) You seem pretty great so far.
0:55 in Tech Mech might need to be a bit less loud, though, because it is pretty loud compared to the start. Otherwise I like the song. It might need a bit more structure as well, such as the ending being a bit similar to the start or keeping elements from the start until the end.
Not sure if I am a bit fan of Tar since it's not my style, but it seems like it would fit well in some video games, such as villages.
My favorite gotta be Another. It totally reminds me of movie music. Actually I wonder if it should be used for some calc game trailer or something?
Also sorry for taking so long before listening to your stuff lol. I finally got through many of the songs posted since last Summer now.
