Practice a lot more so your actions are smoother.
At 0.27 it seemed very obvious that you pulled the hankie from you pocket, and at 1.18 it was obvious the red hankie was in the other hand. Either work on making it smoother, or drop the red hankie bit do you need the red hankie or can you keep going with the blue one?
I didn't see the point of the phone bit, even if it was used as misdirection it was too out of place.
I couldn't really see the liquids changing colour in the glass the first time I watched it. Either adjust the lighting (or have a
light cube in the glass) or get a bigger glass.
The big card's production and the newspaper production was done well. However once again I couldn't see the point of the yellow hankie.
Still all the problems can be overcome with practice and trial and error. Your clearly putting the effort in and thats whats important.
Keep us posted on developments. Good luck.
