Your performance is surprising to be honest...
I recreated your mission, but it seems your launcher can't reach orbit with that much fuel. This is what I had when I tried:
Actually I had a bit more, 56%, I made a mistake, but this is still far below what you showed:
From your screenshot you rather had around 75-80% of remaining fuel.
From this screenshot, you still had a lot of fuel when you crossed the orbit of the Moon:
This is far from being optimal, it's best to burn all the fuel while you're still close to the Earth, that's the Oberth effect.
Your launcher is not bad, I tested, it can do it, but we can't accept a suspect performance.
Tip: You can easily increase your rocket's performance by adding a third stage.
For the rest, if you need advice don't hesitate to have a look at the
tutorial.
Last thing, when you show your ending velocity make sure you show it at one of the specified marks:
It's not a big issue if you are not
exactly at the mark, but try to be as close as possible.
