I recenlty downloaded Affinity Designer, a Graphic Design program on sale which is a good alternative to Adobe Illustrator. I bought it to not only each myself graphic design, but to create "fantasy what-if non-protypical schemes for my favourite locomotives. However I am unsure of where to start. I know are drawings of said locomotives to use and paint such as on Trainx, but how would I photoshop things such as perfect vectors of Railroad company logos onto the locomotive, while keeping the various line showing through?Are there any good online visual tutorials online such as youtube how to illustrate road schemes onto locomotives?
