Very pretty and bright looking.
Have you checked your seams?
This has been mentioned here more than once, but it's still worth doing just to check on your "personal measurementd" - Mary Ellen Hopkins' term -
cut three strips 2 inches wide - they only need to be about six inches long
sew them together with your 1/4 inch seam - press like you usually do - measure -
the three strips sewn together should measure 5 inches -
if they measure more or less, then you need to do some adjusting with either how you cut or how you sew -
Some of the places where differences can happen:
In the original cutting - where do you put the line of your ruler?
When I cut a "two-inch strip" - even though I have the line at 2 inches on the fabric, it's a smidge wider than that because of the extra width gained from the distance the rotary blade is from the edge of the ruler and I sew with about a "real" 1/4 inch seam.
I've seen people use the lines on their mats as guides - the fabric they are cutting off is not under their ruler - so they might end up with "skimpy" two-inch strips
But if you are cutting "exact" two-inch strips, maybe you need to sew a "scant" quarter inch (which is somewhere between 3/16 and 15/64 of an inch)
Your pressing looks nice. If seams aren't pressed properly, little tucks or pleats can gather there also, and make the block "smaller"
