Oooo.. Fresh meat.. I like how you guys (and girls!) over at LBL are sharing your work. Very good stuff. I enjoyed looking at the last round of students.
Couple critiques, I'll break them up into three cut parts.
1st cut - no qualms, looks fine, no effects in here?
2nd cut - couldn't stop looking at shadow of spoon on face and shoulder. ick. match the blacks, and shadow density and blur level. If you had a spoon, why not shoot reference of the spoon held up in front of your face at the proper distance? That way you would know what it looks like when it's floating in space.
3rd and last cut - fine, but the dissolve or quick cut from 3D to live spoon looks kinda quick, and you can tell when it switches. Maybe do a longer dissolve between 3D and live action plate, so you can minimize the abruptness, or instead of having it pause, throw the spoon in the air and catch it, and then matchmove the spoon as it's falling.. You'll be able to fake it better as the motionblur will hide the split between 3D and 2D. Looks like there's a shadow from the original hand that dropped the spoon shadowing your face.
Very cool, and a good first start.
