I gave the model a coat of primer from the the spray can. Later my daughter helped me with the colouring of the model and the details.
I used 1 mm styrene to build a model of this culvert. This is my very first work with this material and my very first try of modelling anything based on a prototype. Here is the result.
Honestly I’m not too happy with the result. After trying to add some texture to the concrete part failed and I have stopped the work on this part. I will look for a different prototype.
