I didn't care too much for "Day by Day", though. Seemed like a lot of the parts clashed with each other and made a bit of a mess. Sometimes it helps to write out parts on paper, or in notation software first. If you can.
"In my dreams" is perhaps the most blatant ripoff of Forrest Gump I've ever heard. Charming
A New Angel in the Sky is very nice. Sounds like there's a heavy Silvestri influence here as well, though. Still it's a nice little composition.
You are good at string writing. The arrangements around the piano dominated pieces are organic and well done. Not too overpowering or muddy, and gently flowing most of the time. Not just a bunch of stacked triads like I hear most of the time in many other demos. Good!
I think all three are excellent. The arrangements all sound great to me. Maybe "Day By Day" is a teeny bit clutterred, but then again, maybe not. I don't hear Forrest Gump at all in "In My Dreams." But either way, as Maraxalamanta, says, it's charming!
