The ship looks very very good and I think is one of the best refit Type 23 frigates I've seen here.
Its very interesting how you chose HMS Richmond.
I have noticed that you have made a slight error with your original image. HMS Richmond was the first vessel of the Type 23 frigates to have an engine upgrade. As a result, the FWD uptake on the mast was redesigned to be more triangular. Please see attached the image below that has the adjustment.
Please don't feel dis-heartened. This is a very unknown adjustment due to the lack of images of her refit.
