It should be up to you rather than your school which subjects you take- I have experience of being forced to take GCSEs I hated, so I know how you feel. If you really don't want to do a language and you don't think it would be of any benefit to you, stick with your original choices. As you said, languages will always be something you can pick up later on if you need to. However, at least consider taking language because they're very valuable, and textiles and art are pretty narrow choices since they're so similar. If you're interested in fashion design, maybe do textiles and Spanish, since that would be better than German as far as fashion goes. It's worth remembering that you're only in Year 8, so it's very likely that you'll change your mind on careers at least once, and having a broader range of subjects will be more useful to you if that happens.
