I think you points are great!!
Often times I will pin the row together and then baste the points where the seams meet and take a look at it. It it's off I can quickly remove the basting threads and try again. Once it looks good I can stich the entire row. When you have a lot of seams coming together in one spot it's hard to get things right with all those "ridges" there.
I find my main problem is that my cutting isn't always perfect; it it were things would line up more more precisely. But hard as I try my cutting never comes out perfect (or even close enough so that things line up as they should).

Your sample looks good. Mine actually get better each time. I try really hard to do the best I can and try equally hard to accept imperfection. When I started quilting three years ago a friend told me that I could stress and take out every imperfection but that could lead me to give up quilting. I try to remember that.

I make sure everything is cut correctly and then i pin everything im a heavy pinner

I did not see your imperfections I thought it was very good

Thank you.

I starch my fabric with heavy starch.....was in a class once when the instructor ridiculed me for making my fabric so stiff. My seams turned out perfect......it washes out, so don't know what her problem was. I also use a scant 1/4 inch...just a few threads less. Beautiful block!

“Practice Makes Perfect”. Old saying but still true.

Accurate cutting and squaring pieces up and then pressing your seams. I usually press to the dark side, though sometimes it is necessary to press the seams open so there is not so much bulk. Nesting the seams and pinning if necessary also help. Once you get the hang of it you can do without the pins. Let the seams meet each other and you should be good.
I have gone to using the Accuquilt system for cutting my pieces perfectly every time and that too has helped a great deal.

No one has posted this yet, so I will ...

I've never seen that method before, DJ. Thank you for sharing, and I will try it for sure.
