Mummel, you have done well but you could do better.
You should have a plan for your capture order. In the beginning of the game, you capture a lot of ammo points. Well it's not that bad, because you will need them for shrek and Mp-40, but there are 2 fuel points near your base, you should capture them earlier.
Your units control in overall also need some improvements, you let some volks stay idle. Try to practice group your units in different numbers and call smoothly, slow is smooth, smooth is fast.
Next is early engagements, you won a medal for this. But you should keep in mind that you won because the Brits player didn't blob his troops on you. If his troops is blobed and support by lieutenants and captain, I think you won't have a chance, even with your mass volks.
Stay on that building is not wrong, because it has windows on all side. But you should take care of your MGs.
You put your paks in good positions but you didn't take care of them very good too. Besides when your volks see that armored car, they should move to in front of your paks positions so you can ambush it and finish it with Panzerfaust later.
Don't use right click or click attack with Geshultzwagen (just call it G-wagon then), use right click then hold to see their range and use it at nearly maximum, I mean you should have put your G-wagon further from the truck and let your troops make sight for G-wagon.
Recrew your paks or not is your choice, but you should have recrew that in most situations.
Keep fighting to see more cunning, (abusing) and challenging opponents in the future.
