Violin and Accessories Reference Pictures

Hello guys and girls

we want to show and provide you some high res reference pictures which will be helpful if you are modeling a violin (or maybe you are inspired to do this now). They were created by me (Thilmann LePoer – bastART). Included are photos of all views (and details) of the violin + bow, shoulder rest and wood resin views. There are two packs one low res (jpg, 2016×1134, 6.62 Mb) and one high res (png, 4976×2800, 215.51 Mb)
Here are some examples:
