Do you plan to eventually upload them to: train-fever.net
Texture wise, there are numerous repaints of existing / modded trains on that website, if it’s not something you can give time to / or are that good at, I am sure others are willing..
It doesn’t look too bad! Yeah, the textures could be better, but then again, there are so many modders out here, and there are so many different liveries in the UK…maybe someone will help you?
I guess the edges of the 43 could be a bit softer. If you’re able to do that, it’ll be a nice mod!
