Hey airedale,
Don't worry about not getting too many criticism at this point. You are just starting out so criticising your images does not have much effect at the moment. The main thing for you to do is to practice, practice, practice with making different things and trying out different tools and settings in anim8or.
Your violin looks good for a beginner! its good to see you are already trying out different materials and textures.
As spicy noted the images are very small, and the violin quite in the distance so it is hard to tell what is going on.
Maybe you can try rendering with shadows to get to know setting up a scene a bit better!
Keep at it, and dont let a lack of comments get you down, its how everyone starts out
