Hi Michal!
You already perform a very lovely job like to get the vehicle number (at the rear-top corner on the both sides of the vehicle) looks dirty and worn-out, but IMO, not the division marking at the left side and in front of the vehicle, since they still looks so clean...
Also the hanged uniform at the rear-left side (near vehicle number) look a little bit shiny. You may make it flat just like the helmet that already looks very nice.
Overall, your work is stunning and very inspiring, mate!

Not like you, my first SdKfz 251 was very bad in assembling process since that's the first time I deal with tracked vehicle, cracked and broken by myself... and the result? I buy a new one with a similar model
Many thanks for sharing and can't wait for your next project!
Warm regards from Indonesia,
Garry
