Thank you for the advice Steevo. In fact, i was inspired my some Matupeco's design for the Sevilla competition, and if i had had more time i would have done a more complex kit.
I think that emblem would work better as a watermark, with a shape adapted to the shirt.

I like the idea but I think with the new (old) badge it would look better.

I think the skyline would maybe work better with it being more subtle, maybe as a watermark.

The design detail/emblem on the right of the chest is ok. Not a great fan of it. I don't think it works on the shirt. I think it works better inside the collar.
