Congratulations for being one more brave modeller passing the finishline here. Your second-hand Autoblinda ended pretty well in my opinion and the point here is whether you enjoyed making it and that only counts. Yes, there are a bunch of impresive models on the go and I believe we all are learning a lot from them. And from now on, everything is up to you. As you are interested in improving weathering you can practice on your Autoblinda or you can even start a new build if you want. You know making a second entry is NOT mandatory but desirable, specially when you have spare time for it means fun.
Hats off to you for finishing your build amigo.
