1st of all, ur link is broken, looks like you zoom in a porting of it and link that, here is the correct link:

second, i am not a tuner or a expert but i have "basic" knowledge on how to read them.
Just by looking at ur signature ur car is euro spec, euro spec and us spec fiesta st are tune differently (MAP vs MAF) but since they have the same motor and turbo, then there should be similarities between logs.
One thing that sticks out like sore thumb is the wastegate dutycicle. if both specs use the same turbo/wastegate/wastegate spring/preload etc, then that wastegate dutycicle looks weird compare to any cobb ots tune log. Your wastegate duty cicle hits 90% duty cicle at boosting it up, then falls to his face and goes back to 48ish% to 52ish% by red line, on must tunes that i have seen with the stock turbo, wastegate duty cicle just go to between 75 to 80% dutycicle boosting up then goes down to 70% and stays there until redline.
Also, your STFT is all over the place, dont know if it of the tune, or byproduct of the low boost.
LTFT is showing a negative number, most logs i have seen and mine, show 0% when you push the accel to 100%, indicating a exhaust leak maybe.
Here is a good read for anyone that want to know if your logs look good, thanks to the guys at stratified:
