Cut downs for stronger pieces

I am not sure if I have posted about finding the heart of a larger piece and cutting it down to create a smaller better piece. Something I do often, particularly if a piece is just hanging around or has not sold and I reconsider its strengths and weaknesses.  I put it on the floor and try a variety of  frames to isolate areas to see if I can find areas to save. Its not uncommon to find a few strong  8x10s  from a larger weak piece.  Another reason I like to paint on boards when I can - so easy to take to the chop saw.

Original sketch - too much foreground

8x10 cut down that I think (hope) is stronger

Thought I would like this start better in square format 12x12 - now to finish the piece

20x30 stretched canvas with poor composition 

Tried 14x18 frame and think I found a stronger composition 

Marked and cut canvas - but accidentally tore it pulling off frame

White glue spread on doorskin to remount

Re-framed, torn area mended using acrylic gel and paint - now to decide what it needs to finish
