It looks like the transmission is tilted up on the engine side. (the transmission's input shaft won't go into the pilot bearing on the flywheel or easily slide into the clutch's splines without proper alignment, see below.)
Move the block supporting the transmission so it supports the transmission _parallel to the engine's drive shaft_.
(when I did my clutch, I had a jack supporting the engine and a second jack supporting the transmission.)
One other question:
Before you installed the clutch, did you try to put the new clutch plate on your transmission's input shaft to check for an exact fit on the splines?
(I remember someone who got the wrong part in their clutch kit or ordered the wrong kit by mistake a few years back.)
take care,
