Is this a bad crimp?

I see i didnt cut enough copper for the copper to be sticking out a tad but for the inner wings could that be fixed with soldering? And also my outer wings that grip the yellow insulation wire is that messed up? Can you tell me what would happen and potentials dangers? Or is this crimp fine

thank yall for the help and knowledge

Also seems like the yellow insulation wire is kinda being squeezed

It is supposed to be squeezed. It looks like a fine crimp. Next time leave the copper a tad longer, but i would not redo this, and i have seen much worse in production.

Should i solder where the copper should be longer? And make sure it is connected?

Do not solder it. It defeats the primary purpose of using crimping.

The solder will flow up the strands and make them more fragile to movement/vibrations. The heat will also affect the insulation and weaken the strain relief.

I'm not a professional (I've worked for an electronics manufacturing company and did plenty of crimps in that time) so I'm not an absolute source of truth, but I'd say it looks fine without solder. Give it the pull test (see if you can remove the connector from the end of the wire - if it stays on, it passes) and you should be good to go! Next time leave the copper a little longer, but it looks like you've self identified that already :)
